Why does phosphorus have a larger first ionization energy than sulfur? Select all that apply. a) According to Pauli's exclusion principle, the last valence electron of sulfur is destabilized because, it is spin paired. b) The statement is incorrect because the general trend left to right in a row is for the effective nuclear charge to increase. c) The last valence electron of phosphorus enters an unoccupied 3p orbital. d) The last valence electron of sulfur enters an occupied 3p orbital.
