show me the MOT in simpler form of helium.

If we were to form He2 molecule from 2 He atoms, we need to apply LCAO-MO method on their TWO 1s AO's, each AO having 2 e, giving 2 MOs, a bonding sigma MO (sigma-BMO) with 2 electrons in it, and an ant-bonding sigma MO (sigma-ABMO), also with 2 electrons. The bond order = no. of pairs of e in BMOs - no of pairs of e in ABMO, will be ZERO, hence no such moleculecule can ever exist.
