- As a general rule, MX molecules (where M represents a central atom and X represents terminal atoms; n = 2 5) are polar if there is one or more lone pairs of electrons on M. NH3 (M = N, X = H, n = 3) is an example. There are two molecular structures with lone pairs that are exceptions to this rule. What are they?arrow_forwardA. What is the electron-pair geometry for P in PCl5? _____There are ____ lone pair(s) around the central atom, so the geometry of PCl5 is ________.B. What is the electron-pair geometry for S in SF4? ______There are _____ lone pair(s) around the central atom, so the geometry of SF4 is ________.arrow_forwardAtom A has 4 valence electrons.
