H Formal Charge

Postby ElizabethP1L » Wed May 23, 2018 1:05 am

Hey, everyone! Is there a reason why the formal charge for Hydrogen is never calculated? I've noticed the solutions manual never mentions a formal charge for H. Thanks in advance!

Hydrogen does not have a formal charge because it is a stable atom. It only has one electron in its shell. When taking the formal charge it would be:
V-(L+1/2B)
1-(0+1/2*2)=1-1=0
The zero indicates a neutral charge.

Hydrogen really only has one electron even when bonding and there is no exception to that, so when Hydrogen has only one electron (which is always the case) it has a formal charge of 0

I understand the formal charge would be zero. However, why don't we label it as such? When other atoms in the Lewis structure have a formal charge of zero we indicate it. Would it be wrong to include it?

I don't think it'll be wrong to include it. If you feel like you have to include it, go for it! But I'm sure when it comes to tests the TAs will know what you mean. But just to be safe, I would. (:
