Is a chemical bond that involves the sharing of electron pairs between atoms.
00:04
These electron pairs are known as bonding pairs.

Here we're looking at the lowest structure of the nitrite ion, so we can draw that below.
00:12
So we have nitrogen, switch out to a better pen, the lone pair, single bond, oxygen atom.
00:29
We have a formal negative charge on this species.
00:34
And so what we can have is resonance here, so we'll look at some resonance on a new page.
00:38
So when we have resonance, this is just the delocalization of the negative charge.
00:48
We can move bonds around, move electrons around.
00:52
So we essentially just get the mirror image here, although that isn't always the case with resonant structures.
00:58
But here it is...
