A lone pair of electrons takes up space despite being very small. Lone pairs have a greater repulsive effect than bonding pairs. This is because there are already other forces needing to be taken into consideration with bond pairs.
So to summarize: Lone pair-lone pair repulsion > lone pair-bond pair repulsion > bond pair-bond pair repulsion. This makes the molecular geometry different.
The lone pair creates repulsion between the molecules attached to it and distorts the shape.
The lone pair pushes bonding electron pairs away.
The molecular geometry of H3O+ is Trigonal Pyramidal because it has 3 bonding pairs and 1 nonbonding pair (lone pair)
Tetrahedral bond angle of a molecule which have a lone pair electron is 107, smaller than regular 109.5, due to the repulsion of electrons of lone pair.
Trigonal pyramidal (the EG is tetrahedral but one side is a lone pair)
The lone pair creates repulsion between the molecules attached to it and distorts the shape.

The lone pair forces bonding atoms away from itself
The lone pair pushes bonding electron pairs away.
The lone pair pushes bonding electron pairs away.
The lone pair pushes bonding electron pairs away.
A lone pair of electrons can affect the molecular shape by repelling bonded pairs of electrons, causing distortions in the molecule's geometry. This can lead to changes in bond angles and overall molecular shape.
It takes up space like an "invisible" atom.
The molecular shape of ammonia (NH3) is trigonal pyramidal. It has a lone pair of electrons on the nitrogen atom, causing the molecule to have a distorted tetrahedral shape.
