Bonding in Polyatomic Ions and Compounds

[@tdewitt451]

that's a really great question. the extra electron gets stolen from another atom. it will usually get stolen from a metal atom that's nearby, because metal ions don't hold onto their electrons too strongly, so they're easy to steal from.

[@LogicLoomYT]

You are a diamond.... I think I will probably make u my chem teacher, like 30 minutes every day.... Your videos are addicting! The concepts that you explain are usually so tough, and you make it so darn easy. You're a hero!!!!

[@michaelhernandez2075]

I never realized that teaching was an art form until I started watching your videos and feel like a blind man that has regained his sight. Thank you.

[@belkiskennedy8664]

You really are the ONLY online teacher I am able to follow and actually enjoy listening to! Everything becomes so much easier to understand. I never understood how covalent bonds can be ions. Thank you!

[@SilenceInTheBliss]

I want to cry -- you make things so easy to understand. You are SO CLEAR...couldn't be clearer. Thank you!

[@fantasybrb7154]

I love how you teach, you are very genuine when you teach and you have helped so many. You are a wonderful person. :) Keep sharing your knowledge with us :) And please continue to stick with your teaching tecniques.

[@emg6219]

This guy is super! Not only did he help me get a background to help my son but when my son watched the videos he understood it completely. Teachers should use his videos as a resource in their classes

[@Thegamer-yp7qq]

correct me if if iam wrong Oxygen must have double bonds how it be one bond with( H) ?

[@FineFeatheredHomestead]

I do - and I tell students which episodes to watch to correlate with the textbook. Great suggestion, BTW! We're watching Ionic vs. Molecular in the next class before heading to VSEPR Theory...when we create the models in class. I'm a big fan of these video lessons as well as his perspective on textbook publishing.

[@77fuqua]

Your videos are straight to the point and the visuals really make the concepts stick. I cannot thank you enough, because of your youtube channel I am actually enjoying my college chemistry class! :)

[@zzz-bb5wp]

“They can steal an electron from smby else” 🤣🤣 🤣suddenly feel they are so cute and alive

[@tdewitt451]

no. a covalent compound is what you call all of the atoms together, like H2O or NO2 are both covalent compounds. covalent bonds are like the glue that holds together the atoms in a covalent compound.

[@apos2870]

@jorge becerra Hi Jorge, from my understanding, it depends on the number of valence shells an atom has. For example, in the case of hydrogen, it only has one valence shell, and that first valence shell can only hold 2 electrons max, so once hydrogen has two electrons it can share in a covalent bond, it will be "happy". In atoms that have more electron shells, the the 2nd and 3rd valence shells EACH have max electrons of 8 (so if an atom had all three electrons shells complete, it would have 2+8+8 = 18 total electrons). To satisfy Oxygen (O), for example, since it has two electron shells, and the valence shell being the second shell, it would need 8 shared electrons to be happy in a covalent bond. Hope this helps!

[@Chirp-chirp]

@@apos2870 isn't the valence shell just one which is the outer shell and not the second one?

Indispensable channel for science students. Subscribed.

[@hananbasheer7720]

This is my first time to understand the polyatomic ions ... really i appreciate the way that you teach its really interesting ... thank you very much

[@AngilasGuy]

Oxygen is PISSED! Great video. I took chemistry last semester and got by, but I'm reviewing your videos to try and solidify everything so I don't lose it. Keep em up!

[@woodnyalerte4039]

I literally just want to give you a big hug. Thank you so much for your videos!

[@ashutoshjha9490]

Buddy..your teaching way is just amazing .You have cleared all my doubts in a spectacular way and beacause of you , a spark of interest to learn chemistry has been enlightened in me.....

[@soapmactavish5677]

u are the best teacher ever, u should teach at my school

[@mohamedelsayed2857]

My teacher didn't explain how does Polyatomic Ions bond and He told me just memorize it. I really wanted to know why does it have negative or positive charge thanks god, i found you and i really liked your way of teaching.

[@adamhogue4419]

samdee pride That is very rude and judgmental of you to say.

[@winivikingdom3654]

@samdee pride wtf is with you wrong? 😂😬

[@failyourwaytothetop]

LOL when a teacher says that they don't know the answer to the question.

[@Chirp-chirp]

oh my gosh I know right! They just say it's "too advanced" but like how else am I supposed to learn it? Why would I just memorize something I don't understand...

[@910385103858]

Dude your explanations are clear and meaningful SUBSCRIBED!

[@salwaramzy9985]

I did pray for you today because you did a great favor for me to understand a lot of things that was extremely hard to understand. May god bless your life!!

[@udehjosiahsnowwhite7761]

Wow. I've searched for this..I love how you really teach practically.

[@nosi6887]

Thanks!

[@tdewitt451]

I WISH you could deduce this stuff from first principles. Unfortunately, I'm showing an example in this video that really only makes sense after the fact. So it's a pain, but you really just have to memorize the different polyatomic ions, the atoms in each, and their charge. It's a total pain, I know.

[@haydenryan7833]

I spent a whole chemistry class thinking about this. Then u explain this in 10 minutes! Thanks

[@sohamlonkar1026]

I was struggling to understand this for many days.but now its crystal clear....Thankyou sir

[@MegaAwesomeToast]

This guy is awesome.

[@shakimaro]

MegaAwesomeToast And hot. don't forget about the hot part.

[@nazinazanin5929]

You are a gem! Such people are really rare in this world.you are literally a perfect example of a TEACHER."one who cant explain anything in a good way, he himself hasn't understood anything ". thats how all our schools or colleges teachers are, but you are a super talented n best teacher ever. Omg i lack words to describe ur perfection....the way u explain so way too easily n interestingly is everything one wants...pls take care we all love you n need ur help..waiting to see more of ur helpful vedios.❤

[@Dhruv45124]

I am a 9th grader and I had this doubt for a long time, I knew some basics of bonding and valency. This cleared all my doubts about polyatomic ions. Thank you so much 🙏 . I subbed!

[@science-y9209]

hey chemistry teacher , how can you be soooo nice . my teacher should fell shame😠😠😠. plzzzzzzzzzz keep on making . you are a hero , a diamond before the eyes of god . keep on spreading your contagious passion for science . cuz of you , I have learned a lot more than i had ever before

[@shafali5461]

This teacher is a rare kind of gem 💎 so easy to understand with this teacher, my teacher fail to teach chem , but now I started loving chem, thank u handsome

[@governmentofheadstone1963]

what makes an atom a metal and a non metal and a metalloid. like, what's the reason behind.

[@governmentofheadstone1963]

I have clicked the link but the page ain't opening. hope you'd see my comment and answer to my questions. THANK YOU!

[@sepxz99]

Omg thank you so much Tyler! My teacher in school doesn't even bother to answer my question and you've really made my day :D

[@bharatarya4919]

Great bro. You are doing a great job for humanity with your hard work and knowledge.

[@wafiqwafiqwafiq3532]

I'm in 2020 and still refering this channel to get the most relevant explanation of chemistry

[@felicianickolas9686]

You're awesome! Your videos are extremely helpful. My professor sucks so I'm basically relying on your videos to help me do well in my Beginning Chemistry class. Keep up the good work :)

[@Fernando-el4td]

Best professor ever. Kudos to you

[@rawahafatiha5492]

Really appreciate the way he enjoys everything he teaches. God bless you sir ❤

[@GiangiUS75]

Congrats! You've explained the topic in a very easy way! For me (I'm a beginner) it was understandable! Thank you!

[@melbagilman3961]

You explain this so well! ~ thanks!

[@beauwilliamson6211]

Thanks man, your videos are awesome. I've been subscribed for a while now, and you've made things simpler for me. Wish you a happy life. Thanks again!

[@ibnzaki2025]

I wished I found your videos earlier! You explain the concepts, which look very hard in a creative and easy way. Thank you so much!!

[@ultravidz]

I can't thank you enough man! This question has been on my mind all week!! Love your work

[@bmwaldner]

I LOVE YOU. Wish you were my chem teacher. Thank you so much. Cannot express my gratitude.

[@astrodima5324]

OK BUT I HAVE BEEN STRUGGLIN WITH HOW POLYATOMIC IONS ARE FORMED UNTIL I WATCHED THIS VID THANKS LOVE THE WAY U EXPLAINNNN!!!❤

[@gameroid2.060]

[@dinosmart1111]

What would I do without this guy? Answer: I have no idea!

[@hwnann98]

I love your teaching method 😭❤

[@cherihaggerty8333]

You're incredible at explaining things!

[@soknanhorn215]

You...are...the...Chemistry...God! (And I think your last name suits you because...YOU GOT THE WITS!) Great thing about your videos is that...you know the content...and also your pedagogy. As a teacher, knowing the stuff is half important, the other half is explaining it to other people so that they get it. Great work!

[@alissa7760]

Amazing video, thank you so much for ur help. I wouldn’t have been able to survive Gr12 chem without u ugh

[@anuvratpatil1371]

i genuinely really hate chemistry and hence never took interest in understanding it. but during my mid terms i watched all your videos and ended up getting an a+ in my exam. you make chemistry so darn easy. thank you so so much

[@dougwestimaging9025]

Let’s begin to acknowledge who the real OG is.. this homie right here

[@sarahn651]

Wow. this is what i call teaching, thank you so much for being exactly what i need to learn chemistry

[@vonyegbulam]

nice. i wondered how you have fewer electrons than protons in your previous video, but this video explains why. thank you.

[@cheskajoyce541]

[@Nadia-mk9qk]

not what i was expecting ;)

[@tamaralindsay9460]

I think your videos are awesome, by far much better than my professor. Can you please do a full video on the lewis structure?

[@itsFarawaySkies]

This answered all my questions and then some. Thanks man! Finals coming up and you got me through a lot of this crap this semester. I'm just thankful I only have to do Chem I then I can get back to my computer shenanigans.

[@EH_888]

I really love your videos. They are a great help to me as a study tool!

Hello Mr. DeWitt, hope you are doing well! thank you again!

[@bingodesign1870]

Sir you are a really brilliant chemistry teacher I love your teaching experience and method in which you teach that's owesam

[@bingodesign1870]

My teacher didn't tell me about Polyatomic ion bonding that how does it actually happens but you told me thank a lot you are really great teacher

[@ayausama1088]

you are the best teacher thank you very much

[@gabrielrojas8718]

I thank God for finding you!

[@JoeChen]

thanks you so much for explaining why there is a charge on polyatomic ions! I never thought of the fact that it got it from somewehre else I saw looking at it as if it was by itself

[@Shineingrock7]

How does it pull an electron from the environment? I know that because it needs one more to remain stable it will want to attain it, but does this mean that there are unused electrons about waiting to be snatched up all over the place? And I think it would have been cool to show that gained electron with a different color than black to show that it came from elsewhere.

[@Chirp-chirp]

i think it's like with ionic bonding but the metal atom that the electron was taken from is already attracted to something else so somehow it doesn't stick to the atom taking it?

[@SecundaXV]

I love these type of video where its soo understandable

[@muchachoachileas3038]

you are awesome!!! dude. I adore you.

[@funkybear7243]

I wanted to know what is the difference between Polyatomic Ions and Molecules? Epic video man👍

[@tdewitt451]

The Upcycler Great question! So a molecule is just a group of atoms that are all connected together. Polyatomic ions are made of groups of atoms connected together, so they are molecules too. Polyatomic ions are special because they have an electrical charge. So you could say that a polyatomic ion is just a molecule that has a charge.

[@Thegamer-yp7qq]

+Tyler DeWitt correct me if if iam wrong Oxygen must have double bonds how it be one bond with( H) ?

[@Okayyyyyyyyyyyyyyyyyyyyyyy-l8n]

He is explaining such an important concept and all i notice is that his middle finger of left hand is raised when he makes a fist😂😂

[@tdewitt451]

The dative case? Indirect objects? Can you elaborate?

[@edniz]

This is exactly what I was looking for!

[@mal7221]

lol chem genius bad at counting... I doubt it ! love your videos, you're a life saver. Please keep it up

[@EsaJennifer]

My STAAR test is coming up in 16 days! This is like the major test! Can you please ma a video on AUFBAU i have no idea what that is and i only like to see YOUR videos because i actually learn.

[@Bountysmash]

Thank you so much! you explain very well, my chemistry teacher doesn't explain this very well!

Thank you so much! I'm eternally grateful!

[@sparshbaliyan5011]

Hi sir! U know its very nice to see your videos. It really makes me more than happy. I don't know why but I see an elder brother of mine in u. I feel like I know you from a very long time. Sir, I live in India so it would be difficult for me to meet you but surely I will meet you one day. By the way I am currently in class 11 and I just want to contact you but sir I don't know how should I so can u please start that thing I mean can you cantact me please cos I don't know how should I begin a conversation with you. I read your comments but it made me sad that you made them 5 years ago. I don't know where u live where are you now where you teach nothing. I just know that I see somewhat like my family in you. It may seem funny to you but really sir trust me I am writing this comment by heart. I don't know whether u will read this comment or not but I will keep trying because 5 years is a very long time. But if you are reading this then please sir just reply once. Its more than just a request. Thank you sir. U got a place in my heart.

[@funkybear7243]

Legend Tyler, thanks mate👍

[@askasenoo4789]

some really sick stuff. thnx man

[@AlucardSlice]

Great Teacher!

[@muyaad]

Thanks for the vid, from your explanation I understand why Nitrate has a negative charge

[@jc6812]

You're videos are absolutely awesome 100%. If you were my future Chemistry professor I'd sign up for your class just from watching this video. Everything is clearly explained so the concept can be easily grasped and having to sit down and listen to you for 10 minutes and a half isn't a chore because you're lively.

[@Lolin6911]

U R GREAT!!! u r basically duin mah homework 4 me, and xtra. i reely wanna do some thing to do with physics when i finish secondary, so could u plz do some vids on higgs boson and wats occurin at CERN. it would realy help as im tryin 2 lern more than im meant to in yr 9. thx.

[@janethuot2359]

I love you! ❤️ I’m going to school after ten years and I’m struggling. You’re my hero. 🦸‍♂️

[@ivanmf3443]

At around 5:20, while explaining OH-, you say that Oxygen gets that last electron from elsewhere, and that is the reason the whole ion has a charge. But what does "elsewhere" is?

[@sheshab]

Thanks alot , Do you have a video about naming in-organic compounds ?

[@Spottino08]

It's a great video, well done! Though I was wondering how Carbonate works. I tried to find it out but it seems different?

[@ahmedalkarkhi]

ur an awesome teacher

[@kathiel5073]

This is the 1st time in watching your very clear and helpful videos (from Scientific notation to this video) I have been confused. I heard you say the O electron takes an electron from the environment. I might have missed something, but not quite understanding from where that electron comes or why. The videos on ionic and polyatomic bonds are great. Chem class has now gotten to covalent bonding and my mental bonds are definitely NOT forming!

[@Chirp-chirp]

I know this was 5 years ago but to anyone who has this question, he mentioned in the comments it's from a metal atom. I see it sort of like how ionic bonding works except the metal ion doesn't bond to the O atom and just goes along with it's day.

[@palpalithito]

I am learning a lot and easily . I did not find the problems to write formulas with transition metals.

[@katherinesmith7871]
