According to molecular orbital theory, the ground state electronic configuration for He₂⁺ is ($\sigma$_1s)² ($\sigma$*_1s)¹.

Question

Quizplus · Accepted Answer

He₂⁺ has three electrons. According to molecular orbital theory, two electrons fill the bonding $\sigma_{1s}$ orbital, and the third electron goes into the antibonding $\sigma^*_{1s}$ orbital, resulting in the configuration ($\sigma_{1s}$)² ($\sigma^*_{1s}$)¹.
