Which diatomic molecule or ion has valence electron molecular orbital configuration provided below? [core electrons](σ_2s)²(σ*_2s)²(σ_2p)²(π_2p)⁴(π*_2p)³ A) B₂ B) O₂- C) O₂²⁺ D) Ne₂ E) Li₂

Question

Quizplus · Accepted Answer

The provided valence electron molecular orbital configuration corresponds to the oxygen ion, O2-. The filled molecular orbitals include the σ and π bonding orbitals (S1U1B12, S1U1P12, S1U1P14), as well as the σ* and π* anti-bonding orbitals (S1U1B0, S1S1P0, π*S1U1B12). The total number of electrons in these orbitals is 16, which matches the number of valence electrons in O2-.
