The mass of an atom is determined by the combined mass of its protons, neutrons, and electrons. Protons and neutrons are the primary contributors to the mass, while electrons have a negligible mass in comparison.
The number of protons
The mass of an atom is determined by the sum of the masses of its protons, neutrons, and electrons. The protons and neutrons are located in the nucleus and contribute most of the mass, while the electrons, which have much less mass, orbit the nucleus. The mass of an atom is typically measured in atomic mass units (amu).
No protons and neutrons
the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.
Mass of an atom = mass of protons + mass of neutrons
The mass of an atom is determined by the combined mass of its protons, neutrons, and electrons. Protons and neutrons are the primary contributors to the mass, while electrons have a negligible mass in comparison.
The sum of masses of protons, neutrons and electrons.
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 number of protons
For a stable atom, no. of protons= no. of electrons no of neutrons= Atomic Mass- no. of protons
For a stable atom, no. of protons= no. of electrons no of neutrons= Atomic Mass- no. of protons

Protons and neutrons account for almost all the mass of an atom. Electrons have much less mass compared to protons and neutrons.
