Question

why lone pair occupy more space than a bonding pair explain as a example of NH3 ammonia​

Answer 1

Explanation:

lone pair electrons occupy more space than bonding electron pairs because lone pairs are more spherical than bonding electron, therefore they repel each other in which they end up taking up more space. ammonia has four electron pairs and ti co-ordination graph of nitrogen is based upon Tetrahedral arrangement of electron pairs. there are just three bounded groups therefore there is one lone pair.

please mark me as brilliant ☺️‼️

Answer 2

Answer:

Lone pairs are located in orbitals that are more spherical than the orbitals in which bonding electrons reside. So, lone pairs of electrons take up more space than bonding electrons because they are only attracted by one nucleus, which implies that they more spread out at a shorter distance from that nucleus.
