WebDec 17, 2014 · The bond strength in dihelium is about 7 orders of magnitude lower than that in dihydrogen. As antibonding orbitals are more antibonding than bonding orbitals are bonding we would not expect these to form. The attractions which overcome this partial antibond are dispersion forces. Experimental verification of dihelium can be found in this … WebEnergy is released when the electrons associated with the two hydrogen atoms form a covalent bond.
