A lone pair of electrons can distort the molecular shape because it occupies space around the central atom and exerts repulsive forces on nearby bonded atoms. Unlike bonding pairs, lone pairs are localized and occupy more space, leading to adjustments in the angles between bonded atoms. This results in changes to the ideal bond angles predicted by VSEPR theory, often causing a distortion in the molecular geometry to accommodate the presence of the lone pair. Consequently, molecular shapes such as bent or trigonal pyramidal can arise from the influence of lone pairs.
A lone pair can significantly distort the molecular shape, particularly in molecules with a central atom that has both bonding pairs and lone pairs of electrons. The presence of a lone pair generally leads to a repulsion that is stronger than that of bonding pairs, causing bond angles to be altered. This distortion is often observed in geometries like trigonal pyramidal or bent, compared to their idealized counterparts. The extent of distortion depends on the number and arrangement of the lone pairs relative to the bonding pairs.
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.
It is a bent molecule because of Oxygen's lone pairs
The lone pair creates repulsion between the molecules attached to it and distorts the shape.
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.

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 shape would be pyramidal because of the lone pair nitrogen has
