Writing Ionic and Covalent Formulas

[@daprin2660]

understandable thank you very much

[@mrcausey]

You're welcome! Thank you so much for watching.

[@haydenza2792]

i just wanna say thank you its my first year in highschool and i have been missing a lot of school because i was sick these videos are a life changer thanks

[@mrcausey]

You're welcome. I am glad the videos are helpful. Thanks for commenting it very much appreciated.

[@28kittylover]

thank you so much! I have a test tomorrow and this was much simpler and easier to follow than my chemistry teacher is!

[@larsley6268]

I am a student at College of Micronesia.. i want to say that this is very helpful and i recommend all the students who are struggling in Chemistry, especially my colleagues to watch Mr. Causey's video.. they're all Awesome and Helpful.

[@mrcausey]

+Rave Leya Thank you so much for the kind words.

[@ricodiaz8099]

what, where is College of Micronesia?

[@aaaaammmmmyyyyyy]

omg MIND BLOWN! i never understood until now!! thankyou mr. causey !!!!

[@PreciousIam]

never understood chemistry until I started doing these videos....awesome

[@waldensun9818]

OMG Mr. Causey you are the best you make me understand everything in 10 minutes better than in 1 hour of classtime!! Thanks so much dude!

[@waldensun9818]

+Mr. Causey hey what is the difference in phospurus and phosphate and all other ide or ate or rus? please help anybody? thanks!

[@dabananaman9086]

@@waldensun9818 -ide is used for non-metal compounds generally. For example, Chlorine forms a chloride ion, so NaCl is Sodium Chloride. -ate and -ite are commonly used for polyatomic ions of Oxygen. -ate is used for the ion that has the largest number of Oxygen atoms.

[@brandymiles7104]

I know this is old but I have a science exam tomorrow and this helped me so much, Thank you!

[@mrcausey]

Many people need all the explanation because they have gaps. After 30 years of teaching I have learned to review everything. A lot times students don't have the whole picture.

[@jamiel3876]

Im taking Intro to Bio Chem for prereq into a college nursing program. I decided to get this class out of the way and take it this summer, online which was seeming like a big mistake. Not only is it online, but my teachers English and explanations are awful. Thanks so much for the video, I understand it quite a bit more than our book!

[@mrcausey]

You're wecome. You can should checkout mrcausey.com

[@jamiel3876]

Thanks i will!

[@hakamtaha6370]

+Mr. Causey hi mr.causey Ihave question can ask

[@dolam]

Very helpful! Thank you very much. You are a lot easier to understand than my Chemistry Professor.

[@cjdude1017]

Thanks, you are very good at explaining this concept. Now I understand.

[@mrcausey]

cjdude krause You're welcome.

[@anli_ace]

This video was actually so hilarious, and I'm a little more confident now, which is saying something, coming from a student. Thank you for making these videos; I should probably watch more!

[@flashkitty4486]

this video is very useful for the students who are confused in writing molecular formula

[@a7laro2ya]

Now I know how to remember LEAD...PEANUT BUTTER...my favourite! thanks for the awesome lesson. Any chance you do one on one tutoring online?

[@NLD20001110]

Great video, first I was confuse on how it works

[@TonyStark-te1wy]

Hello Mr.causey I am skipping a year 9f chemistry and going into Ap chem and just basically need a complete run down over the basic chemistry and begginer chemistry that explains everything. Could you please send me of all the videos you think I should start watching from basic to advanced. Thank you

[@Touchyoulove01]

thank you Mr.Causey

[@TonyStark-te1wy]

Hi again is there any place where I could just get a list of all the chemistry vocab and there defenitions it would help so much.. thank you

[@XInfinityXify]

thanks! Helped me with my Science Exam!

[@mrcausey]

First never use parentheses with an element, only with polyatomic ions. Ca has a +2 charge and Cl has a -1 charge but the charges must balance thus you need another Cl to get -2. +2 + -2 = 0, balanced. CaCl2

[@habibty123]

very helpful thank you

[@xXcHoCoLaTe98Xx]

this was SOOOOOO helpful. thank you so much.

[@gamerprods124]

Thank you so much! Very informative!

[@Adam9837]

Its to do with the number of electrons in the respective elements outer shell. Phosphorus is in group 5 and therefore wants 3 more electrons to fill its outer shell. Oxygen is in group 6 and therefore wants 2 electrons per oxygen atom. A covalent bond is the sharing of electrons. We are trying to find a subscript value with means they both have full shells. Phosphorus trioxide isn't really phosphorus trioxide it is tetraphosphorus hexoxide . (tetra =4) (hex = 6).

[@mrcausey]

It's not that you can't, it's just customary to remove the a from "ao" combinations. If you removed the "i" from dioxide you fundamentally change the meaning of the word. The "di" is important to the meaning. Remember science is not absolute. It's a set of general rules and ideas that have exceptions.

[@sabrinayang1724]

Why does your intro remind me of FRIENDS? haha! :)

[@ahmedkhaledmedia273]

can you please help me with balancing manganese (iv) sulphide. thanks for the videos

[@shube6092]

thank you my teacher

[@nityanandkushwaha9490]

THIS IS VERY FOR THE STUDENTS AND I LIKE IT.

[@mrcausey]

+Nityanand Kushwaha Thank you for watching and commenting!

[@mehrinali6622]

thx...you helped alot.

[@beshoywassef3611]

You make chemistry really easy thank you very much god bless you but I still have trouble naming the ion it's a little confusing I don't know which one is covalent and which is not I hope you make another video explains this thanks keep up the good work

Thanks

[@mrcausey]

You are welcome!

[@DiLLZGFX]

Thanks so much!

[@mrcausey]

You're welcome. Thanks for watching.

[@SamirAhujaGamer]

My teacher taught me to memorize valencies of elements and then write formulae. When is that method used then?

[@KdramaDhara]

Thank u!!

[@moffatandanje1201]

if sodium phosphate is written as Na3Po4,please show the steps involved and how the cation and anion is equal to 0

[@jammie146]

this is great. thank you :)

[@robertacevedo6055]

My science teacher is awful. He comes into class reeking of liquor every day and doesn't teach us anything, just tells us to go work. Thank you for making me pass, Mr. Causey.

[@mrcausey]

+Fuzile Gaming You're welcome. Thanks for watching.

[@alexanderreddick7090]

I got it- thanks!

[@mrcausey]

You're welcome.

[@fionanguyen1817]

That was great

[@carthneylaukonjr.9755]

how do one know the number of the subscripts of the element or ion when writing the formula?

[@purpleification123]

What if you are not given the prefixes in a covalent instance. In my textbook, it says that phosphorus chloride's formula is PCl3. I don't understand why there are three chlorides. Similar to hydrogen oxide (water) I know its simple but how do u find the covalent formular as H20 without prefixes.

[@mrcausey]

If your textbook is referring to PCl3 as phosphorus chloride, it is a poor textbook. How can you distinguish between PCl3 and PCl5? The reason there are usually three chlorine atoms on one phosphorus atom is because chlorine only has one bond and phosphorus has three bonds. Never call water hydrogen dioxide. Water is water. Check out my videos on Lewis dot symbols and oxidation.

[@isaactimothy7004]

You helped me so much :) So funny when you yelled Aluminium Acetate xD

[@mrcausey]

Sorry about the excitement. I just get carried away.

[@iznatayyab5775]

there's a 3 under the nitrate ion in the first example. The charge of the nitrate ion is -1 so wouldn't it have a total charge of -3? and then lithium is +1 so how come it's balanced? I have a chemistry paper tomorrow and i am sooooo gonna fail...

[@robindheeraj5534]

sir please make a video on nomenclature equations

[@mrcausey]

Did you check my playlists?

[@mrcausey]

You're welcome.

[@mrcausey]

What for? Why?

[@destinymartin8500]

thank you thank you thank you

[@MUZIKability]

i'm confused...in 5:46 why is it not Ca(Cl2)2? hehe.....i'm just confused with that part....because i thought they should criss-cross? * both 2's are subscripts.

[@canadianforever14]

so cool

[@angelamador1171]

i got 10/10 thank you

[@keurinrin16]

where did you get 3 hydroxide ions?:D

[@karuppiahsivarasan5504]

Ur a genius and a half

[@danielquach9358]

thanks, earned a subscriber XD

[@mrcausey]

Daniel Quach Thank you!

[@sirisaacnewton4985]

Using crisscross method to get it easily.

[@mrcausey]

The crisscross method does not teach the logical concept that is needed to perform the task with more difficult compounds. Poor form.

[@sirisaacnewton4985]

Yes i know that..thank you for your response. i like your videos here because i learn more..

[@mrcausey]

Sir Isaac Newton Thank you for watching.

[@sirisaacnewton4985]

Mr. Causey I'm teaching chemistry and physics in our school that's why I'm always watching your videos here for my lessons..Thank you sir!!!

[@zachbishop22]

what grade are you guys learning this I'm in grade ten

[@mrcausey]

Humping Moose There are all ages learning from my videos. The information is mostly geared to a beginning chemistry course.

[@justincrawford1207]

college......

[@gennkill]

why is CO2 named as carbon dioxide and not carbon doxide?

[@hammadk15]

how do u know that lithium is a cation ?

[@mrcausey]

Well, first of all metals are cations and metals are cations because the metals give up or lose electrons.

[@mathislifeforme5721]

download the all equation and formula of chemistry

[@juanaalvarez7955]

can you help me

[@Rdizzle512]

i love you..

[@AyDeN636]

thumbs up if ur usin this to study for chem test

[@annieb2744]

Hi Mr Causey Good video but too much talking. Would be great to get straight into it!

[@louielambretta389]

lol dude no way you are over 30, although thanks for the video.
