Most of the mass of an atom is found in the nucleus which contains the protons and neutrons.

The Hydrogen atom. Beware, Hydrogen has an atomic mass based on one proton, as it doesn't have a neutron. So Helium has a mass of four times Hydrogen.
The mass of an atom is primarily determined by the combined masses of its protons, neutrons, and electrons. Protons and neutrons contribute most of the mass since electrons have negligible mass. The exact mass of an atom can be found by adding up the masses of its protons, neutrons, and electrons.
The great majority of the mass of an atom is found in the nucleus, where protons and neutrons are located. The nucleus is incredibly dense and accounts for almost all of the atom's mass, while electrons, which are much smaller and lighter, contribute very little to the overall mass of the atom.
The majority of an atom's mass is found in its nucleus, which is located at the center of the atom. The nucleus is composed of protons and neutrons, which are much more massive than the electrons that orbit the nucleus.

The positive charge in an atom is found in the nucleus, which contains protons. Most of the mass of an atom is also located in the nucleus, primarily from the protons and neutrons that make it up. Electrons, which are negatively charged, contribute very little to the mass of an atom.

the electron
Essentially all of the atom's mass is in the nucleus. In the lightest atom, that of hydrogen, it's about 99.95 percent. In the heaviest naturally occurring atom, that of Uranium238, it's about 99.979 percent.
The majority of an atom's mass is found in the nucleus, which contains protons and neutrons. Electrons, which are much smaller in mass, are located in the electron cloud outside the nucleus.
