12. Molecular Shapes & Valence Bond Theory

Determine the number of electrons found in the π_2p orbitals for the dioxygen dication, O₂²⁺. 

Using a MO diagram, write the electron configuration for the P₂ molecule

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?

Suppose that you have 16 diatomic molecules or ions with the valence molecular orbital arrangement shown here (figure 1), but with different numbers of valence electrons. species 1 has one valence electron, species 2 has two valence electrons, etc. classify each as diamagnetic or paramagnetic.

Construct the molecular orbital diagram for H₂⁻ .
