Abstract
We have analyzed the stability of various oxides of K and find that K2O2 is the most stable one. The additional stability is traced to the presence of oxygen dimers in K2O2 which interact to form molecular orbitals. Other oxides such as KO2 and KO3 which also have dimers/trimers of oxygens are found to be less stable. This is traced to the shorter O–O bonds that one finds in them which gives rise to a significant coulomb repulsion between the electrons on the oxygen atoms making up the dimer/trimer, making them less stable.
