Why do lone pair electrons have a greater repulsion strength than bonded elctrons?

I think that lone pairs have a greater repulsion strength because they occupy more volume!

The electron repulsion between lone pairs is stronger than the repulsion between bonding pairs since lone pairs occupy a larger volume. In other words, since lone pairs occupy a larger volume, they are able to push down on the bonded pairs, which is why lone-lone pair repulsion is stronger compared to bonding-bonding pair.

Hi! I believe this is because bonded electrons are more localized, specifically to the orbital/bonding region in between two different atoms and is further from the nucleus than lone pair electrons. The lone pairs are closer/attracted to one nucleus/atom. Therefore, there is more repulsion from the lone pair electrons. Hope this helps!

Lone pairs occupy a larger volume than bonds do, so they push down and exert more force on the other bonded pairs.

Just to clarify, lone pair electrons have more repulsions so therefore that angle is wider, correct? In that case, we just have to know that concept? Or is there certain angle degree that is associated with lone pair repulsion?

Hi! Yes you are correct, lone pair repulsion is greater than bonding pair repulsion, so the angle of the remaining bonds are smaller. The angle degree for lone pair repulsions tend to vary, so I think just knowing the concept should be sufficient. Hope this helps!

Oh good!Yes thank you so much, Chanel

Lone pairs have more freedom and are able to occupy more space compared to bonded electrons.

The position of lone pairs is more variable than the position of electrons in bonds. As a result, electrons in lone pairs can move close to electrons in bonds and repel them, while electrons in bonds can't move as close to where the electrons in lone pairs usually are and repel them as much.

Since lone pairs occupy more volume, they cause more repulsion.
