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!

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

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! <3

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.

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 ❤️

[sriharshak]

Your explanation is so deeply thought complicated and awesome

[totalcriro]

I have gained a lot of skills unintentionally. Thanks for this video❤

Thank you so much sir. I don't think you get how much u do for us students:) hope u have a good day, I know u won't be seeing this comment but I wish you the best!

Excellent video, visualization, and explanation of the Valency, the valance and the chemical reactions for the elements that you exemplified. It was really easy to follow.

[michaelloran]

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

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?

[AjibolaElizabeth]

You are a great tutor sir
Kudos to you

[anwar]

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

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

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

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

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

[fatiman]

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

[saravanakumark]

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

Been a while since you made a chemistry video.
