The sum of all Protons and Neutrons.
The nucleus makes up nearly all of the mass of an atom, with over 99% of its mass concentrated in the nucleus. Within the nucleus, most of the mass is found in the protons and neutrons, while the electrons surrounding the nucleus contribute very little to the overall mass.
The nucleus is the part of the atom made up of protons and neutrons, and it contains nearly all of the atom's mass. Electrons, which have much lesser mass, orbit around the nucleus.
This would be the NUCLEUS.
Most of an atom's mass is concentrated in the nucleus, which is made up of protons and neutrons. While electrons contribute to the atom's overall structure, their mass is negligible compared to that of the nucleus. Thus, the nucleus is responsible for nearly all of the atom's mass.
Very nearly all of the mass of an atom is found in the nucleus in the form of Protons and Neutrons. Electrons and "binding energy" contribute a tiny amount of additional mass.
