A neutron and a proton combine to form a nucleus. How does the mass of the nucleus compare with the sum of the masses of its individual particles?

A. The nucleus has less mass, because matter is converted into binding energy.

B. The nucleus has more mass, because matter is converted into binding energy.

C. The nucleus has less mass, because binding energy is converted into matter.

D. The nucleus has more mass, because binding energy is converted into matter.

Demarion Maxwell · Answer 1

Among the choices, the correct answer is A. According to Einstein's equation E = mc^2, the mass of an atomic nucleus as compared to its individual components is lesser. The missing mass is called mass defect. The missing mass happens because in the fusion process, some of the matter is turned into binding energy.
