Use the following MO diagram for Be₂,Be₂⁺,and Be₂^-.Based on this diagram, A)Be₂⁺ is more stable than Be₂,and Be₂ is more stable than Be₂^-. B)Be₂^- is more stable than Be₂,and Be₂ is more stable than Be₂⁺. C)Be₂⁺ and Be₂^- are both more stable than Be₂. D)Be₂ is more stable than either Be₂⁺ or Be₂^-.

Question

Quizplus · Accepted Answer

The MO diagram shows that Be₂⁺ and Be₂^- both have lower energy than Be₂. Therefore, both Be₂⁺ and Be₂^- are more stable than Be₂. Option C is the only choice that includes this observation.
