A lone pair contributes to molecular shape by occupying space around the central atom and influencing the arrangement of other bonded atoms. It exerts repulsive forces that are generally stronger than those between bonded pairs, leading to adjustments in bond angles and overall geometry. This results in molecular shapes that may differ from those predicted by simple bonding theory, as seen in structures like bent or trigonal pyramidal configurations. Ultimately, the presence of lone pairs alters the molecular geometry to minimize repulsion between electron pairs.
