Lone pairs are more repulsive than bonds because their charge density is spread out more, whereas electrons in a bonding pair are specifically held in a region right between the two bonded atoms. Because the electrons in the lone pair are able have their charge density more spread out, they repel other electrons more strongly which causes them to "need more space" in molecule shapes.
Hello! Lone pairs of electorns on molecules occupy more space than bonded electrons since they have significant repulsion strength they are attracted by the single nucleus, hence illustrating that through a short distance they are spread out from the nuclues which they are attracted to.
