Lone Pairs

Why do lone pairs take up more space?

Lone pairs have a stronger repulsion than bonding pairs because bonding pairs are farther away from the central atom since it needs to be connected to the sharing atom. Also, lone pairs are delocalized, meaning they are more spread out than bonding pairs and therefore fill more volume. They are also only attracted to the central atom, whereas bond pairs feel attraction to two atoms.

They have much stronger repulsion that lone pair bonding or bonding orbitals thus they take up more space or rather push the other bonds away

Lone pairs are not confined to a bond; the electrons exist in a cloud of probability that takes up more space and thus has a greater repulsion in order to maximize the amount of space between each other.
