The presented values of bond energy and its length indicate that in either H + 2 and H - 2 ions are lower than in the case of H 2 whereas the value of the ratio of effective kinetic energy to Molecule R eq (a 0 ) E bond (eV) potential energy significantly larger than 1. Interestingly, the ratio for H - 2 takes a value significantly lower than 1. We describe this reduction as the predominantly resonant character of the covalent-ionic bonding.
