Assume that the MOs of diatomics from the third row of the periodic table, such as P2, are analogous to those from the second row.

a. Which valence atomic orbitals of P are used to construct the MOs of P2?

One of the molecular orbitals of the H2− ion can be sketched as follows:

a. Is the molecular orbital a 𝜎 or 𝜋 MO? Is it bonding or antibonding?

(b) How many of the MOs from part (a) would be occupied by electrons?

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

Consider the H₂⁺ ion. (a) Sketch the molecular orbitals of the ion and draw its energy-level diagram.

Consider the H₂⁺ ion. (b) How many electrons are there in the H₂⁺ ion?
