Just preparing for my competition, our teacher barely taught us how to do Lewis structures when the compound isn't electrically neutral, you are really always there to save the day!
Sir. I find your channel by accident when I'm strugling with the general chemistry. Thanks for your help and please keep making video like this. Honestly, it's really helpfull.
@@wbreslyn I was the first viewer. I am currently teaching bonding and I find it all your related video's very useful and students find them very useful too as it is straight to the point and you are left with no confusion.
Thank you (for being first and for using my videos). I started making videos for my students and they helped me understand what helped them the most. I organized my bonding videos on my website at www.breslyn.org/chemistry/bonding/index-bonding.php . --- Dr. B
09:50 For those atoms that can accommodate more than an octet: How can we know _how many_ additional electron pairs can we move towards it and when to stop? I mean, in your sulfate ion example, you kinda got away with it by assuming the charge of the ion. But suppose we don't know that charge yet, and all we know is that there is one sulfur atom and four oxygen atoms surrounding it, and we want to figure out the structure and the charge from it. How can we do that? Oh, and what if the number of valence electrons is an odd number? (as for example, for nitrogen oxides, NO and NO₂)
I may be calculating the formal charge incorrectly, but when I checked the formal charges of the atoms in the first Lewis structure for the sulfate ion, I get a 2- charge for that structure also. If that is correct, I don't understand how formal charges help to sort out which structure is better in this case. I have the sulfur atom with a 2+ charge and the oxygen with a 1- charge (times 4) for a total 4- charge on the oxygen. That adds to an overall charge of 2-.

I'm also preparing for the incoming Chemistry competition in 2023, I hope you did well

Your channel really deserves more subs than this sir

I'm glad you found my channel! All the best in chemistry!
That’s funny. I am currently studying for my OnRamps Chemistry class as you uploaded your video
All the best with your OnRamps! --- Dr. B
I am living for how you say "valence" please never change that.:) also thank you for this video as i am strugggliinng.
sup
Thanks! Valence is one of my favorite words. I also like saying "Cyanide".
I cannot thank you ENOUGH for this video!
Hello Dr B
Your video's are very clear and super helpful for teaching. Thanks for your awesome resources
Wow, thanks for the kind words. I think you were the first viewer! --- Dr. B
Wayne Breslyn and I’m the second

5:32 im confused, doesnt C only have 4 valence electrons?
im sorry i got it i was just dumb 2 days ago

Thank you prof. Breslyn!
Welcome!
Thank you! Now this makes a lot more sense :))
Glad it was helpful!

You're very welcome!
Thank you soo much💯
No problem!
You saved my life
Sir No3 and No2 has -ve charge but in some cases in co complex they can bear +ve charge...can you explain this...tnx
I may be calculating the formal charge incorrectly, but when I checked the formal charges of the atoms in the first Lewis structure for the sulfate ion, I get a 2- charge for that structure also.

I assume the reason may be the second structure has more atoms with a formal charge of 0?
omg u have saved me
Happy to help!
Donot displayed writing on the this produce drastic disturbenc to the viewer's
this really save my life or i gonna be failed in chem for 100 per
It is not clear picture due to display writing on screen
Do you mean at the end of the video? There shouldn't be anything extra during the video!
