Nuclear fission is the phenomenon of splitting of an unstable nucleus of a heavy atom into two medium-weight nuclei due to bombardment with slow-moving neutrons, with the release of enormous amount of energy.
Nuclear fusion is the phenomenon of combining or fusing two or more lighter nuclei to form a stable heavier nucleus with the liberation of enormous amount of energy.
Now consider four materials - and with mass numbers and respectively.
