The sum of protons and neutrons in an atom is called mass number.
The answer depends on the atom! The total number of subatomic particles in an atom of an isotope is the sum of the mass number and the atomic number of the isotope; the mass number counts the protons and neutrons together, and the atomic number recounts the number of protons, which in a neutral atom must be the same as the number of protons.
The particles are protons, neutrons, and the nucleus inside of the atom Nice helping u >_<
Physics has not managed to discover a particle that accounts for mass
Neutrons are located in the nucleus of an atom, along with protons. Together, neutrons and protons make up the majority of an atom's mass. Electrons, which are negatively charged particles, orbit around the nucleus.
Hey! The excepted banacular is gay. Don't call them atoms that's just mean.

The two subatomic particles added together to determine the mass number of an atom are protons and neutrons. Protons have a positive charge, while neutrons have no charge, but both contribute to the mass of an atom.
Mass of an atom is determined by the no. of protons+ no. of neutrons in the atom.
The two subatomic particles you add together to get the mass number of an atom are protons and neutrons. Protons have a positive charge, while neutrons have no charge, but together they contribute to the mass of an atom.
The atomic mass of an atom is determined by the sum of the number of protons and neutrons in its nucleus. Protons have a positive charge, and neutrons have no charge. The total number of protons and neutrons in an atom's nucleus is called its mass number.
The two parts of the atom that have a mass of approximately 1 atomic mass unit (amu) are protons and neutrons. Protons are positively charged particles found in the nucleus of an atom, while neutrons are neutral particles that also reside in the nucleus. Together, these particles make up the majority of an atom's mass. Electrons, on the other hand, have a negligible mass compared to protons and neutrons.
Protons, neutrons and electrons.
Nucleons are subatomic particles found in the nucleus of an atom. They include protons and neutrons. Protons are positively charged particles, while neutrons have no charge. Together, they determine the mass and stability of an atom.
The protons and the neutrons, because those are the only particles in the atom that contain quarks.
Mass of an atom = mass of protons + mass of neutrons
protons and nuetrons
Protons and neutrons are the subatomic particles that have mass and are included in the calculation of the atomic mass number. Electrons have very low mass compared to protons and neutrons and are usually not included in the atomic mass calculation as they contribute very little to the overall mass of an atom.
