7.7 Molecular Orbital Theory – Chemistry Fundamentals

WebKeeping the overlap of orbitals in mind, the bond in molecular hydrogen is average as far as covalent bonds go. Molecular oxygen's double bond is stronger at 498 kJ/mol primarily because of the increased orbital overlap from two covalent bonds.

You have to really, REALLY try to get any sort of bond with helium at all under anything resembling normal Earth conditions, and even then the resulting compounds are wildly unstable (much too unstable to exist naturally). So all helium on Earth exists as just regular old free gaseous helium. nimsoft support matrix

"WebAug 3, 2014 · He2 can be promoted into higher-energy bonding orbitals, thus giving a nonzero bond order and a “reason” to form. For example, a possible excited-state MO electron configuration for He2 would be (σ1s)2 (σ1s*)1 (σ2s)1, giving a bond order of (3 – 1)/2 = 1. Thus excited He2 molecules can " - Bond order of helium
