Finding the Number of Valence Electrons for an Element
Вставка
- Опубліковано 25 тра 2013
- An explanation and practice for finding the number of valence electrons for elements on the periodic table. This is a key first step for drawing Lewis dot structures for molecules.
Looking at the Periodic Table, atoms have a regularly occurring number of valence electrons based on their Group number.
Group 1: One Valence Electron
Group 2: Two Valence Electrons
Group 13 (also called 3A): Three Valence Electrons
Group 14 (also called 4A): Four Valence Electrons
Group 15 (also called 5A): Five Valence Electrons
Group 16 (also called 6A): Six Valence Electrons
Group 17 (also called 7A): Seven Valence Electrons
Group 18 (also called 8A): Eight Valence Electrons*
* Although in Group 18, the element Helium only has two valence electrons.
In general we do not draw Lewis Structures for atoms of the Transition Metals (Groups 3-12).

OK brigadier 😂
My teacher made this so complicated and it took only two minutes to understand!
+Blue.Bomber shit dude me too
+Blue.Bomber relatable
+Blue.Bomber could have sworn my teacher had the white board filled with equations and shit..... haha i understand
My teacher took us through his life problems.
ikr
Glad it helped. Finding the number of valence electrons is the first step to drawing accurate Lewis structures. - Dr. B
Hi this was helpfull thanks
THANK GOD FOR THIS GUY my teacher acted like this was the worlds hardest concept
same..
all these comments are from 5 years ago and im over here 2021 T^T
Same lol
Me too
Me too
facts I have a test tomorrow and I don't know shit
@@brysonnieto7163 I wish u the best of luck 😼🤚
when your teacher takes a whole class to explain this...
YES
yep
ikr?
Fajer njr I know right!
He says you aren't expected to know the transition metals but that's bullshit. If anyone can explain how I can calculate them with out using the columns that would be great.
You explained it in a very easy way, so I understood them in a minute. Thank you from this lovely, clearly and understandably lecture.
Thanks! Valence electrons are such a key concept in chemistry so I'm glad it helped. --- Dr. B
This comment was 6 years ago so what's happening now may I ask?
Wow why is my teacher making me subtract and do other stuff when she could show me this thanks man! Easy points for my final exam!
Do they give you the periodic table in your exams? Probably not, right? So, it is necessary to know the atomic number of atoms, and hence from it, find it's valence electrons by subtracting it's atomic number from that of the nearest available noble gas
@@isaacsamuel9520 man that was 6 years ago theyre probably not even in school anymore
@@angelgutzz1412 ik that very well but who knows, it may help someone who has the very same question so, I just commented it :)
@@angelgutzz1412 frr😭
@@isaacsamuel9520 I’m pretty sure they give the periodic table
This was so easy, my teacher made this like it was rocket science! Thank you so much
😂😂😂rocket science
Wow why do teachers make my life so much harder instead of explaining like this
Because your mom

I remember doing this video when my channel was new and being happy that it was getting a lot of views. It's sort of crazy that it is still bumping --- 700 views over the weekend, 142,000 this past year.
@@wbreslyn that's cool, you deserve the views you're getting and much more, thanks to you I understand this stuff
This teacher just explained in under 3 minutes, what it took my teacher (online) no less than 5 lecture videos to explain (with each video being about 10 minutes each).
They are like some of these “why if “what if” videos but wayyyy worse just extending a whole topic to 50 minutes when it can be solved in 2 minutes
Thanks for being better than 100% of chemistry teachers
I'd be happy with being better than 98% so thanks for the encouragement! --- Dr. B
THIS IS SAVING MY GRADES! thank you so much ✨✨ you deserve a medal 🥇🎉
It literally took him 1 minute to explain to me what took my professor 3 class periods to explain and I still didn't understand it until I watched this video. You're the real MVP sir
Thank you so much! You just saved my life... I have an exam for College Chemistry on Tuesday. Thank you for making this easier. :)
lol my teacher cant explain this for the whole class this dude says it and i get it in 2 minutes
this is actually soo easy
thank you
Which country you live

Worlds easiest explanation
GOS BLESS THIS GUY........
best of luck for future!!!!!!!!!!
An incredible video that is short, sweet, and to the point
Thanks, that's the best way!
simple and straight to the point. i rlly appreciate it dude you helped me a lot!
I thank you from the bottom of my heart 💓 . I was not able to understand this in my class but understood it here very easily. keep up the good work 👍
Man I wish I could give you more than 10000 likes….. YOU ARE BEST THAN THE REST ❤❤❤❤❤
All your videos are fantastic Dr. Breslyn! Thank you for helping a college student get through chemistry!
My pleasure!
Thanks man I kept on failing assignments about this and my teacher wouldn’t do crap but you made this so easy thanks 😊
Glad it helped!
Thank you so much Dr. B! That was super helpful!
u literally is one of the reason I finished my high school days thinking that chemistry is easy because of your videos! I'm in college now and I still watch your videos!! Thank you!!
Great to hear and all the best in college chem!
I have my final chemistry exam tomorrow and this helped me WAY more than my teacher that explained to me at least 3 times- thanks so much doctor. B :)
Hope your exam went well!
simple, straightforward, and I loved that you gave us a couple to practice as well. thanks so much!!
You're welcome!
Very easily understandable video in less than 3 mins.... Hat's of Sir

Thanks you have gone through a very easy method I have understand it so fastly
Excellent, glad to hear you understand finding the number of valence electrons. This is an essential skill in chemistry! --- Dr. B
Does the M shell have the ability to hold 8 or 18? I'm having trouble understanding Valency because of not knowing this. Please help me, thanks.
8 years later thank you so much
Wish I watched this earlier. Explained it 1000x better than my teacher
thank you so much for this video!
