### NO

For the Lewis structure of NO, it is a radical, and In class today the structure given was:
. ..
:N-O:
..

Is it possible that it can have a double bond instead of a single bond? Would this be resonance?

### Re: NO

You can add a double bond to the NO structure to stabilize the formal charge, but this wouldn't be resonant to the single bond structure b/c a double would transform the structure completely.

### Re: NO

I believe taking a lone pair of electrons from oxygen to make a double bond between N and O is possible and it would make the formal charges of O and N zero (without the double bond the formal charge of N is +1 and FC of O is -1)
So I think creating a double bond would be the way to go

$\dddot{N}= {\ddot{\ddot{O}}}$
(idk how to do the lewis structures sorry sorry I will learn later)

As for the resonance question
resonance means to have multiple bonds in different equivalent locations
I don't think there's another place to put the double bond (there's really only one place for bonding btwn O and N) so I believe this is not resonance (correct me if I am wrong)

### Re: NO

At the end of lecture, the TA explaining this section started drawing the Lewis structure of NO with a double bond. I didn't hear what she said, but I believe a double bond would work. Also, this would not be resonance.
