Draw an MO energy diagram and predict the bond order of Be2+ and Be2-. Do you expect these molecules to exist in the gas phase?
Bond order of Be2+ = 1; Bond order of Be2- = 1/2
Neither can exist in the gas phase.
The bond order of Be2+ and Be2- = 1/2.
Bond order of Be2+ = 1; Bond order of Be2- = 1/2
Both can exist in the gas phase.
