- Hence the diberyllium molecule exists ( and has been observed in the gas phase ).
- Another molecule that is precluded based on this principle is "'diberyllium " '.
- However, the 2s can mix with the 2p orbitals in diberyllium, whereas there are no p orbitals in the valence level of hydrogen or helium.
- If this is true, then why is there no sp mixing to allow for the diberyllium molecule ? talk ) 05 : 16, 28 October 2011 ( UTC)
