Due to this repulsion force, the lone pairs tend to go far from each other in the plane. The electron-pair geometry provides a guide to the bond angles of between a terminal-central-terminal atom in a compound. The steric number gives the electron-pair arrangement for the geometry that maximizes the distance between valence electron pairs. See graphic on middle left. In ammonia, N has 3 bonds and one lone pair of electrons. When the distance between valence electrons is maximized, the energy of the molecule is at its lowest state and the molecule is in its most stable configuration. there are no lone pairs of electrons on the central atom .
