Which term is used to denote the central part of the atom that holds most of the mass?

Explanation:
Most of an atom’s mass is concentrated in its nucleus, the dense center made of protons and neutrons. Electrons orbit around this center and are far lighter, so they contribute very little to the total mass. The nucleus is the part that actually holds most of the mass, while the atom also includes the lighter electron cloud surrounding it. A proton is one of the particles inside the nucleus, and an electron is the lighter particle in orbit; neither alone describes the central mass, whereas the nucleus as a whole does.
