WebSep 12, 2024 · The mass difference, or mass defect, is given by (10.3.1) Δ m = Z m p + ( A − Z) m n − m n u c where Z m p is the total mass of the protons, ( A − Z) m n is the total mass of the neutrons, and m n u c is the mass of the nucleus. According to Einstein’s special theory of relativity, mass is a measure of the total energy of a system ( E = m c 2 ). WebEinsteins well known equation E=m * c^2 shows that there is an equivalence between mass and energy. Besides the electromagnetic force being involved with the electric charges in the atomic nucleus there is also the residual strong nuclear force which is about 20 times stronger than the electromagnetic force at the distances in the atomic nucleus. good dog university west springfield ma
