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 … WebHelium has two electrons; therefore, it can completely fill the lowest shell with its two electrons. If you look at the periodic table, you will see that hydrogen and helium are the only two elements in the first row.
