WebAnswer (1 of 4): Helium(z=2) atom has 2 electrons in its outermost shell. So He2 molecule will have 2*2=4 electrons. According to Molecular Orbital theory ,the atomic orbitals of the two He atoms will combine to form 2 molecular orbitals(1 bonding and 1 anti-bonding). So Electronic Configuration... 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.

Question: Which Is More Stable He2 Or He2+?

Chemical bonding - Molecular orbitals of H2 and He2

WebMay 11, 2015 · A recent paper by S. Shaik reports that a quadruple bond exists in C 2. And hence though the actual molecule has been found, its chemistry is still being studied. Actually, the electrons not in the bonding orbitals are in non-bonding orbitals, not anti-bonding orbitals. Diatomic carbon does not have a quadruple bond but a double bond. WebHeH+ (with two electrons), on the other hand, is a bit (relatively speaking) more stable. It's also the strongest known acid! O2 for example has a sum of 2 and hence is a double bond.
