Electron Configurations Part 3- Writing Configurations

[@cassijo55]

Thank you SO much! Every single video was so helpful! This has probably been explained to me one hundred times but never broken down this way. After three years and 3 different chem classes I finally understand every part of it! Thank you, thank you, thank you!!

[@debbiebiekert]

You are amazing, I have learned more from you in one hour than I have four weeks in Chemistry! Thank you my savior.

[@drewjackson2905]

Very Helpful! My teacher didn’t teach this, just threw it in our face and expected us to already know it.

[@nishmati]

I love how you actually EXLAIN each step, unlike most people who just rush through it. Thank you so much :D It really helped me understand it :3

[@jacqulinjoseph9370]

thank you sir, your level of explanation is very tremendous way

[@BGirlSkirtao]

I am sooooooo grateful for your videos. I was so lost and feeling overwhelmed and your videos helped me greatly. You are amazing!!! thank you!

[@truefighterstv]

You explained every single step! Better then the video which got 1 million views. You are so much better!!!!!!!!!!!!!!!!! thank you!!!!

[@Kiseki0328]

Wow thank you sooo much! I made the most of my studying in a less amount of time thanks to your very well taught video! I hope there are more to come!!

[@abhinavsingh5202]

great work man found this video today and tomorrow is chem exams thanks man. saved my life

[@fardeenrafiq]

Thanks a lot.. I'm so grateful to you. I had a lot of confusions in writing the electronic configurations. You cleared them all... Thanks again..

[@iamjacksrage00]

This is funny because this video is when i finally understood this subject after MANY MANY attempts at being taught by various teachers. Thank you sir.

[@ayeshasamreen5539]

this is the best way of explaination i can say !! i am really thankfull to you.... really love the way how u explain each and every step so clearly... THANKYOU SIR !

[@rohitvarghese20]

Thank You for all your help! I have a chemistry test tomorrow and I didn't know one thing about what to do.

[@riajain8590]

thank you so much! I can actually understand electron configurations now, unlike the other videos which just made it more confusing

[@speeshers]

thank u! u r thee first person that actually helped me explain this to me!

[@kamleshsharma-kh2rx]

Sir how did u find out the 4p square electron at the last in germanium? And also 3p six electrons at the last of chlorine

[@JG-ch3ki]

Omg!! Thank god I found your video I have been studying this for 2 days and I kept getting more and more confused but this video helped me so much!!!! ❤

[@kentchemistry]

Glad it helped!

[@jaydee8959]

wow just great....and you even showed how to convert it to the Bohr model..... you really have a gift

[@sashavukasovich4857]

My high school chemistry teacher could not explain this to a class of 31 in two days and this man can do it to a class of 15,614 in five and a half minutes

[@rafaelhazembuller7084]

No, serious... you ARE good. I wish I had found you earlier in the semester!

[@zlaurat996]

This video has saved my chemistry grade. THANKYOU :-)

[@cynthiamejia8449]

Finally! Someone who speaks my language!

[@RVILLA67]

So many have tried, none are as simple. Thanks

[@sharonjohnson5329]

in nursing school trying to get the basics of chemistry. I never took it in HS. thought it was too difficult then. If I only knew and had you. I can see it now-thanks Sir.

[@puggsoy]

The period's number specifies the sublevel of the s orbital in that period. As you can see in the configuration, the s for Fe is 4s. However, the d orbital for the 4th period is 3d, since in order of energy, 4s comes before 3d. This is mentioned in the two videos before this one.

[@monikagrigorova485]

Best video series on this topic!

[@munyaradzimurapa6738]

WOW. this saved a lot of study time, THANKS SO MUCH!!!

[@pierreevans3617]

hey thanks alot i have this exam coming up next week and your video jus saved me alot of time of studying and but one thing you said 2p twice. you said for the the 2's and 3's lol but thanks a whole bunch!!!!!

[@almagomez28]

Why does it take my chemistry professor 3 hours to explain this?? I was thinking the whole time " oh shit I'm failing this course". With your videos I'm learning a hell of a lot more and now I really hate my boring ass professor.. Thanks for sharing your easy learning methods instead of telling us to memorize the whole damn chart... This rocks instead of reading the textbook..

[@tanmay199929]

Thank you so much for these videos. These really are helpful for everyone. Cheers!

[@jeremyyasin7227]

Dude! these 3 parts are awesome it seems so simple now thanks!

[@tarynb4927]

THank you!!!! You explain it really well and make it so easy

[@edwardhaughney9665]

These are beautifully presented videos.

[@Xogsademindset]

Finally got it, This man is awesome!!

[@AmnesiaPiggeh]

Thank you so much, you've really helped me a lot in Chemistry! :)

[@seanmacisaac334]

Thanks man you helped me learn this in one night for my test tomorrow! (I was sick and missed the unit -_-)

[@faithalondra841]

thank God ! and thank you :)) i've learned a lot. you teach better than my chemistry teacher :) !

[@carlosmolina1059]

Great, great, great videos. Thanks for the explanation.

[@DaesungMars]

I understand how to get the last energy sublevel, but I don't understand how to get 1s2, 2sp, etc

[@mellowyellow7523]

Daesung Mars he has videos you should watch before this

[@superstargamer333]

Best videos... 3 parts r too good😊

[@craftsxox]

You need to be a chem teacher at school!! This was Sooo helpful!!

[@PatrickVo7]

Hi kent, For the (Fe) atom, you wrote 3d^6 as the last past. However, isn't it in the 4 period so shouldn't it be 4d^6? i'm just a little confused of why it is 3 but in the 4th period on the table. Thanks :)

[@fahadaljahadhmy2564]

thank u for explanation but i have a little question about Iron u wrote [Ar] 4s^2 3d^6 what about p-block u didnt write it ?

[@timesplit--ter2742]

+Fahad Al Jahadhmy He did. Watch again.

[@LillyKoppMusic]

Great videos! So helpful! But I have one question: why, in Noble Gas Configuration, after you find the most recent Noble gas, do you start from the highest s-orbital? Why not another orbital?

[@LillyKoppMusic]

Never mind. I see now: because the periodic table STARTS with s... @.@ Duh

[@rongaleo8466]

what you mean as in previous noble gas?

[@jesuscrazybaby]

at last i finally understand this configuration thing!! thanks a lot!

[@notaliberal4738]

Thank you inmensely! 9th grade chemistry can be crazy sometimes!

[@rajeshghatkar8645]

rilly....this is when i've finally understoood d concept

[@x305seth1]

Would the chloride ion's sublevel configuration be simplified to [Ar]?

[@kentchemistry]

That's to easy. You need to write at a configuration for at least 1 sublevel.

[@purple54997]

kentchemistry.com too*

[@prajwalikaprakash5309]

Thanks a lot :D This video helped me a lot. Even Part 1 & 2.

[@timesplit--ter2742]

Only Chloride is the exceptional? How about other elements? It's on 3p5, but it's actually 3p6 as you stated.

[@Lord_Skeptic]

chlorine ion

[@nikhilreddy5123]

i agree with you

[@statwizard]

100% awesome!! Thank you very much for clearing this up.

[@TSalama7]

Thank you so much you are a life savior

[@preetmangat2590]

Ni 28 ( atomic number) configuration is Ar 3d8,4s2 why not Ar 3d10 even d block can hold 10 electron ?

[@slendermansbestie3168]

Thank you so much, this is so helpful!!

[@kentchemistry]

You're so welcome!

[@1ShaneGarvey]

Very clear and concise! Thank you.

[@fu1274]

wow man...thank you so much....it was never explained to me this way...:-) :-) :-) :-)

[@ahmadghazali619]

In Ge 32 you have writen [AR] 3d10 4s2 4p6*instead of( 4p2)

[@hamidshokoofeh]

Only Chloride is the exceptional? It's on 3p5, but it's actually 3p6 as you stated.

[@patnaiksonal31]

How to remember the order of d sub levels? Please help!

[@sashimi6576]

how do you do this without a periodic table??

[@kentchemistry]

It is much harder. Most chemistry classes have a PT.

[@rabiafzal178]

i really like it it helps me alot THANK YOU

[@juanluvisminda9930]

i don't get the part why does Argon have to be the sublevel of Iron ? And Chlourine with Neon? please tell me... I'm on the third year highschool... and we're at this part os science..i really don't understand...

[@timesplit--ter2742]

+Juan Luvisminda Group 18 is noble gases.

[@donnamarie4592]

thank you !!!! This made things very clear !

[@mererveve]

that was very helpfull, and very simplified :) thankyou

[@karynmittens5199]

Very Very helpful! Thank you!

[@stephhrabe6971]

Thank you for explaining that!!!

[@sherjins3241]

but there is a small mistake while taking cl ion

[@izzysam5114]

Thanks !!! Nice explanation

[@tyronchua9212]

thank you sir... your the best!!!

[@hailesanders3321]

You were great, but you should slow down. I had to pause every few seconds and rewind. We're clueless about this! Thanks for helping though!!!

[@cricketworld9713]

can any one tell me how the atomic number of chlorine becomes 18 in this video..?

[@RichardVolke]

Thank you!

[@dalechristopher3917]

great vid!

[@shikhasingh1840]

Thanks very helpful video

[@sangojusandeep1966]

thank you very much you are awesome.

[@DJHA133]

Thank you so much.

[@jmoneymaker96]

chlorine is 17 electrons not 18! Also why is that silver is 5s1 4d10 and not 5s2 4d9?

[@tazmik18]

Thank you so much!!!! i have problems understanding, but you made it so easy!! Thankkkkkkk uuuuu :) :P :D >_< Best video ever! easy to follow!

[@Nicolemuycer]

thank you so much!!

[@lukeerickson2696]

So it would actually be 1s^2, 2s^2, 2p^6, 3s^2, 3p^5

[@saifaliksa8085]

I didn't understand..wheres that 18 came ??:(

[@sweetienena]

Because its not the Cl atom, but Cl ion= (state of gain or loss of electrons). If you remember how to more or less predict an ionic charge from the periodic table, you`d remember that for groups IA the ionic charge would be +1 and for group IIA would be +2. For groups VA to VIII A you would subtract 8 to the the element`s period. Ex: Cl is from group VIIA, so it would be 7-8= -1. Cl has 17 electrons in it`s neutral state,and one extra electron in it`s ionic state. This makes up for a total of 18 electrons. Hence 3p6 instead of 3p5 on the electron configuration.Hope it helps.

[@eyobtesfamariam7965]

+sweetienena Isn't that what he explained in the video?😅😅😅

[@MG-yp3qq]

+Eyob Tesfamariam indeed it was; I was only clarifying the concept.

[@eyobtesfamariam7965]

Alright then😊.

[@sjc8947]

awesome vid thanks alot

[@axelvlain1709]

This explanation is awesome. XD I don't get why our teacher gave this stuff to us for hm. She never thought it and I'm only in 9th grade.

[@axelvlain1709]

But actually I tots understand which ain't norm. So thumbs up!

[@aloksinha3998]

Thank you

[@hardyharboy]

My hero

[@kingzfan2000]

I think this video would have been a bit better if you had just went in order from hydrogen to maybe Neon or something so that people could more easily grasp how the progression works then save the skipping around for maybe the very end or another video altogether

[@mj35k]

woooooowwww you helped soooo much!!!

[@LazyGamersSquad]

It starts at the anode Electrons are lost there And move through the wire And set the load on fire It moved through the cathode And reduce the cation And the anion moves through the salt bridge Back to where? WHERE?

[@kentchemistry]

trouble maker

[@dheerajangadi6126]

Thank u very very much

[@sherjins3241]

very useful

[@aaronsvd]

same here, our teacher just discuss but don't explain how things done with better explanation.

[@anthonyobyi]

thanks

[@ladyfrank3354]

thank you !!!!!!!

[@americapinela7133]

THANK U !!!!!!!!!!!

[@shemi729]

Thnx...

[@nathando2311]

it's a chlorine ion so it has an extra electron.

[@fionagai8468]

Y r u sooo bloody amazing? Haha

[@BookHeal]

Good

[@makm67]

just peeerfect :)
