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.

When a beta particle is released from an atom does the atom gain or lose mass?
When a beta particle is released, the atom's mass remains approximately the same because it loses an electron, which has such a small mass in comparison to the whole atom that it is negligible.
Which particle of an atom has the less mass?
The Electron.
What subatomic particle determines how a atom interacts with another atom?
The electrons, specifically the valence (outer shell) electrons.
What particle of an atom has the most mass?
It would be neutrons.
Which particle or particles of an atom have little mass?
electrons
What particle determines the mass along with the protons of an atom?
The particle is called the "Quark"
The particle that determines the mass of the atom is what?
Protons, neutrons and electrons
What is the particle that determines the mass of an atom is called what?
Protons, neutrons and electrons
What particle determines the name of the atom?
nuclei
Which subatomic particle determines the charge on a nucleus of an atom?
The proton.
Which in an atom has the least mass in an atom?
Which particle? The electron.
What subatomic particle number determines the identity of an element?
The number of protons, which is the atomic number of an element, determines the identity of an element.
What subatomic particle determines whether an atom exists as an isotope?
neutron

What sub atomic particle does not particitpate in the calculation of mass of atom?
Mass of electron is not included for the calculation of mass of an atom.
In an atom what determines the mass number?
The atomic mass number is the sum of the protons and neutrons in an atom.
