Building on from that, if an atom has more lone pairs, then those lone pairs will push down more on the bonded electrons (resulting in more repulsion strength than an atom with only one lone pair or none).
Repulsion strength in an increasing order would be bonding-bonding pair, lone-bonding pair, and lone-lone pair. This means that repulsions will be higher if there are lone pairs involved compared to if there were only bonds.
Lone pairs typically have the highest repulsion since there are no electrons being shared, while bonded pairs typically have the lowest repulsion since the electrons are being shared. Therefore, two lone pairs have the highest repulsion, followed by one lone pair, and bond pairs have the least repulsion.
