Valency

This chemistry video tutorial provides a basic introduction into the concept of valency. It explains how to determine the valency and the number of valence electrons in an element and it discusses the relationship between valency and the number of bonds in a chemical compound.

Just stopping by! Took chemistry years ago and loved your videos. I can still pick up chemistry topics because of you. I'm really happy your channel took off. I knew it was inevitable. Take care!

[@a7medal-harrasi936]

i dont have chemistry although i want to thank this man very much because he is putting his time for doing us stuff that we should have known on our own thank you really much man i really appreciate what you are doing i have been counting on you since i was at grade 10

[@michaelloran]

Geez man Since 2017 I've been watching and downloading your videos nonstop I really appreciate the consistency in terms of your manner of disseminating Chemistry, as you are one if the reasons I became passionate about it and also graduated from Chemistry in college... #Watching more of your videos makes me extremely happy, and I really want you to know that you are really helping millions of people out here like me that formerly didn't have interest in it... #Much love man, and you have repeatedly earned my respect... I wanted to ask do you have a site that you normally publish more of Chemistry related book or videos, I would love more of that ❤️

[@sriharshak481]

Your explanation is so deeply thought complicated and awesome

[@champagnevangi]

I remember acing chemistry in high school because of your videos, and here we are again, years later, tryna ace my exams w the help of your videos!

[@shehzan9263]

You are a great tutor sir.

[@michaelloran]

I really would love you never to stop, you are really helping me....

[@kavi18in]

Thank you for posting. Very helpful

[@r1der589]

thank you you helped me out a lot

[@AjibolaElizabeth181]

You are a great tutor sir Kudos to you

[@LloydSMITH]

Very simple actually !

[@primalpiano7580]

Lloyd Smith Your channel is awesome!!!

[@019saravanakumark2]

After a long time, happy to see ur chemistry video.. Please upload more chemistry videos.. Please post topic of 18 electron rule.

[@yasinhaider9943]

Love your videos!! Just want to point out that at 6:36 you mentioned "Sulfur has 16 valence electrons" which is actually the number of electrons it has. Whereas valence electrons is the number of electrons in the last shell.

[@agroxk]

yeah.

[@Ruatpuia..]

Language mistake

[@sophiea4265]

so helpful,thank you!

[@anwar4227]

YOU AR THE BEST.....DAMN HOW DO YOU COPE UP WITH PRESSURE.....I MEAN YOU KEEP UPLOADING SO FAST....THANKS MAN....

[@dibdej317]

Thank. Great video.

[@mrpuppeteer2834]

I understood this within 50 seconds.. Please make a video on radicals and what they are. Thank you...

[@subwaytoiletgaming762]

this guy knows everything ong

[@rebecajanowicz9056]

awesome video!!! thanks

[@major_kukri2430]

Been a while since you made a chemistry video.

[@chemistrytutorialbysmalik9091]

Nice explanation

[@SatishKumar-yg8ek]

Excellent video,👍👍👍🔋 from India

[@tajuoni8854]

Dear Mr Julio, Your videos are helping me greatly.May God Almighty bless and reward you.Please I would like to see a picture of you.Please send it .You're a gem sir

[@sekaran404]

Thanks!

[@Lowkeyhiman]

You earned a sub😁

[@youthtahiri4009]

very thankful !!!

[@anik3841]

When you say that an element ''wants'' to take or give electrons, what do you mean? Is it a property of the element? If it is, how would we know it?

[@dineshprasadsah5243]

Thank you sir

[@fatiman9552]

Thank you for your videos. Because of you I’m passing my classes!!

[@a7medal-harrasi936]

this is everyone not just you thank god the world has people like you @the organic chemistry tutor

[@fatiman9552]

​@@a7medal-harrasi936 I know. This man is awesome!

[@albertmpese9589]

Now I would love to know how to find out valency

[@yousefahmed8896]

awesome 👍♥️♥️

[@Memes-xm1xy]

for the people who thought magnesium could take 6 electrons to become stable the maximum valency is 4, so it gives the 2 electrons

[@josephcote6120]

Our chemistry teacher in high school taught us a little poem: Little Willie was a chemist Willie is no more What Willie thought was H-2-O Was H-2-S-O-4

[@keishatripathi7763]

omg sameeeeee

[@inderjitmatharu7153]

hi i liked your viedo

[@sandipanganguly2219]

Hello I really like your videos and learnt a lot of things from you I mean if he was our teacher he would complete the whole syllabus twice but still have 3 months left for tests He is a legend

[@ShaivVaishnav]

🙏

[@Yara-fs5ej]

I love you

[@kisho2679]

so what would be the valencies of lanthanides and actinides?

[@Ben-dv8xw]

Starting organic chem 2 this semester. I will be reviewing all these chemistry videos.

[@hkharis07]

My question is if here S is giving 6 electron to oxygen how we can justify that its in its complete octet?

[@rahul1yrago301]

Sir is it compulsory to have 2 electrons in the first shell?

[@IsabelS767]

Yep apart from hydrogen which only has 1 electron in total

[@nimaabdullahi3125]

​@@IsabelS767 what about the second shell is it compulsory to have 8 electrons as well?

[@bombachimica]

@@nimaabdullahi3125yes on the first one 2,second 8 ,third 14 as a maximum

[@user-lf3nv3wd6l]

how do u know how much electrons are on each shell?

[@keishatripathi7763]

it goes like 2 in the first shell then in any other shell max is 8 which is the stable state

[@PoloML]

👍👍👍

[@zephyrgaming865]

I thought electrons cannot be separate

[@d.cdineshkumar7062]

Please Post with subtitle

[@Memes-xm1xy]

we would love to see your face sir PLEASE PLEASE PLEASE

[@derlyswanson8414]

I can learn English easier with you.

[@user-cq9ti3qc9g]

I can t under

[@randoboy7293]

uhh first?...

[@okonkwosandra23]

am sorry sir i do not still understand

[@frantisekvavra4093]

Can you please stop using comic sans? Its pretty annoying. Thanks.

[@josephcote6120]

It's real handwriting with a tablet.

[@kareebmurshid3658]

Shut up

[@user-zp1ft5hr1y]

hydrogene valency is 5.
