In molecular orbital theory, the σ_1s orbital is ________ and the σ_1s^* orbital is ________ in the He₂⁺ molecule.

Question

Quizplus · Accepted Answer

In molecular orbital theory, the σ_1s orbital is filled because it is the bonding orbital formed by the overlap of two 1s atomic orbitals from each helium atom. The σ_1s^* orbital is half-filled because it is an antibonding orbital formed by the overlap of one 1s atomic orbital and one 2p atomic orbital from each helium atom. Therefore, Choice C is the correct answer.

In Molecular Orbital Theory, the σ1s Orbital Is ________ and the σ1s*
