In the LCAO wavefunction for H₂ given below, the second term can be described as "ionic" because $\Psi_{\mathrm{MO}}^{\mathrm{el}}$ = [1s^A (1)1s^B (2) + 1s^A (2)1s^B (1)] + [1s^A (1)1s^A (2) + 1s^B (1)1s^B (2)]

Question

Quizplus · Accepted Answer

The second term is described as "ionic" because it represents configurations where both electrons are located on the same nucleus, either both on nucleus A or both on nucleus B, which is characteristic of ionic bonding.
