this is what my notes say: 'cuz the lone pairs repel the bond pairs more than they repel each other'

so what does that mean? i know they cause the bond angle to decrease, and that they repel the bond pairs, but what does the last bit mean?

also dont the electrons within the bond repel each other too?

lone pairs are closer to the atom than bonding pairs, this is because bonding pairs are attracted by positive nucleus of the atom it is bonded to.
so lone pairs are closer together? so lone pair - lone pair repulsion will be greater than LP-BP repulsion, greater than BP-BP repulsion because distance between electron pairs gets further going from them respectively

I think what you meant in your notes was:
Lone pairs repel bond pairs, more than the bond pairs repel bond pairs.

If that doesn't make much sense, basically:
-All electron pairs repel each other to some extent (in an exam question you don't need to explain the ins and outs of why this is, usually mentioning all bond pairs repel is fine).
-Bond pair-Bond pair repel the least
-Bond pair- Lone pair repel the second-least (not the most, not the least)
-Lone pair-Lone pair repel the most

Usually that's what they'll ask for you to write about in an exam question, that's about it.
