Question

atomic energy

A atomic mass energy is the ​

Answer 1

Step-by-step explanation:

A neutron has a slightly larger mass than the proton. These are often given in terms of an atomic mass unit, where one atomic mass unit (u) is defined as 1/12th the mass of a carbon-12 atom. You can use that to prove that a mass of 1 u is equivalent to an energy of 931.5 MeV.
