Can he2+ exist

WebTwo electrons total, both occupy the sigma orbital, two more electrons in bonding than antibonding orbitals, the compound is stable. Eg: He + He; same mixing as above. Four electrons, two in the sigma, two in the sigma*. Since there are as many bonding electrons as as antibonding, there is no net bond. He2 is not possible. WebWe can therefore use a molecular orbital energy-level diagram and the calculated bond order to predict the relative stability of species such as H 2 +. With a bond order of only 1/2 the bond in H 2 + should be weaker than in the H 2 molecule, and the H–H bond should be longer. As shown in Table 9.8.1 , these predictions agree with the ...
