Nuclear fusion is a reaction in which atomic nuclei merge to&nbsp;form the nucleus of a new atom. The mass of the new&nbsp;atom’s nucleus is lower than the sum of the merging&nbsp;nuclei’s masses, a difference that is released as energy.&nbsp;This is, for instance, the reaction that occurs in the Sun.&nbsp;The energy released during fusion can be calculated by the&nbsp;equation E = Δmc2, where Δm is the difference between the&nbsp;initial and final masses in the reaction, and c is the speed of&nbsp;light. When calculating the aforementioned energy, nucleus&nbsp;mass can be conveniently quantified using the atomic mass&nbsp;unit (u), which is roughly equivalent to 900 MeV&nbsp;(1 u -&gt; 900 MeV). Consider the hypothetical nuclear fusion&nbsp;reaction 222X + 4Y -&gt; 221Z. Note that the masses of 222X, 4Y,&nbsp;and 221Z are 222 u, 4 u, and 221 u, respectively. The&nbsp;amount of energy released in this reaction is
