23. When comparing Be2 and H2: I. Be2 is more stable because it contains both bonding and antibonding valence electrons. II. H2 has a higher bond order than Be2. III. H2 is more stable because it only contains 1s electrons. IV. H2 is more stable because it is diamagnetic, whereas Be2 is paramagnetic. (A) I, II (B) III only (C) II, III (D) II, III, IV (E) III, IV
