Answer:

nucleus

Most of an atom's mass is in the nucleus—a small, dense area at the center of every atom, composed of nucleons. Nucleons include protons and neutrons. All the positive charge of an atom is contained in the nucleus, and originates from the protons.

The mass of an atom is the nucleus.

  • An atom is made up of three components- proton which is positively charged, neutron which doesn't have any charge and electron which has a negative charge.
  • The proton and neutron of an atom have nearly the same relative mass. Compared to these, the mass of an electron is negligible.
  • Hence, nearly all the mass of an atom is contributed together by the proton and neutron which make up the nucleus. The electrons revolve around the nucleus in fixed paths.
