### Clarification of lone pairs

Just wanted to be certain, lone pairs occupy their own region of electron density, yes?

Correct! Think of them as electron clouds.

Yes you're right!
Lone pairs e- are very repulsive (even more than bonded e-) they also have a very large effect on the actual shape of
the molecule.
For ex. If there are lone pairs of e- around the central atom,
the bonds around the central atom will be repulsed and will
move away...so the bond angles are affected by regions of high e-density such as with lone pair e-

lone pairs are a region of electron density :)
