In a nuclear reaction what happens to the mass and the energy during the reaction

Answer 1

In a nuclear reaction, mass is converted into energy according to Albert Einstein's famous equation, E=mc^2. This means that a small amount of mass is converted into a large amount of energy during a nuclear reaction. This process is known as nuclear energy release and is what powers nuclear reactors and nuclear weapons. Therefore, during a nuclear reaction, the mass of the original particles involved in the reaction is not conserved - some of the mass is converted into energy.
