Consider the following second-period heteronuclear diatomic molecule.
Combining the valence orbitals (2px, 2py, 2pz, and 2s) of each of the two atoms
creates eight new orbitals (one 02s*, one 02s, one 02p, one 02p, two л₂p, and
two л₂p) that span the entire molecule and explain it's electronic properties.
Those eight new orbitals exist at six energy levels.
Rank the molecular orbitals of a F2 molecule from lowest (1) to highest (6)
