It would be neutrons.
The Electron.
The atom loses mass when a beta particle is released because a neutron decays into a proton, electron, and antineutrino. The mass of the neutron is greater than the combined mass of the resulting proton, electron, and antineutrino.
A neutral particle in an atom is typically found in the nucleus, such as a neutron. Neutrons have no charge and contribute to the atomic mass of the atom.
The electron is the subatomic particle with the least mass. It has a mass of about 1/1836 of a proton or neutron.
This atomic particle is the neutron.
In the atom the heaviest particle is the neutron but the proton is close.
Which particle? The electron.
An atom with a mass of 15 amu is most likely a nitrogen atom, as the atomic mass of nitrogen is approximately 14.01 amu. This means that the atom may have gained or lost a particle, altering its mass slightly.
These particles are protons and neutrons.
The Electron.
These particles are proton and neutron.
Mass of electron is not included for the calculation of mass of an atom.
Protons and neutrons, which are found in an atom's nucleus, account for most of an atom's mass. Electrons, which orbit the nucleus, have much less mass compared to protons and neutrons.

Neutrons are the particles that contribute to the mass of an atom, along with protons. Neutrons have a similar mass to protons, but they do not have a charge. The number of protons and neutrons in an atom's nucleus determines its atomic mass.
