Answer;

-The energy needed to split an atom into separate protons, neutrons, and electrons

Explanation;

E = mc² The equation is derived directly from Einstein’s Special Theory of Relativity .

Each of the letters of E = mc2 stands for a particular physical quantity. Writing them out in full we get:

Energy = mass × the speed of light squared

In other words:  E = energy (measured in joules, J),  m = mass (measured in kilograms, kg),  c = the speed of light (measured in metres per second, ms-1), but this needs to be squared.
