Consider the H2+ ion.
(a) Sketch the molecular orbitals of the H2+ ion and draw its energy-level diagram.
(b) How many electrons are there in the ion?
(c) Draw the electron configuration of the ion in terms of its MOs.
(d) What is the bond order in H2+?
(e) Suppose that the ion is excited by light so that an electron moves from a lower-energy to a higher energy MO would you expect the excited-state H2+ ion to be stable or to fall apart? Explain.
