WebAug 3, 2014 · Use MO theory (and diagrams) to explain why He2 molecules can come to exist and why they dissociate. And this is from the solutions manual: The ground state MO electron configuration for He2 is (σ1s)2(σ1s*)2 giving a bond order of 0. Therefore, He2 molecules are not predicted to be stable (and are not stable) in the lowest energy … WebUse molecular orbital theory to explain why the Be2 molecule does not exist. Determine it's bond order and whether it is paramagnetic or diamagnetic. Question. Use molecular orbital theory to explain why the Be 2 molecule does not exist. Determine it's bond order and whether it is paramagnetic or diamagnetic. ... H2, He2, He2*, H2-A: ... WebThe helium dimer is a van der Waals molecule with formula He 2 consisting of two helium atoms. This chemical is the largest diatomic molecule—a molecule consisting of two atoms bonded together. The bond that holds this dimer together is so weak that it will break if the molecule rotates, or vibrates too much. It can only exist at very low cryogenic … click to get it
