Question

Answer 1

"imagine that we hae measured the inertial masses of a proton and an electron, separately, and that we then let them come together to form a hydrogen atom. Is the inertial mass of the atom equal to the sum of the masses of the electron and proton? No; it is a shade less. Why? Because in the formation of the atom with the binding together of the proton and electron, the equivalent of a tiny amount of mass escapes in the form of radiation."

Can someone explain why this is?
