The Electron.
The electron is the subatomic particle with the least mass. It has a mass of about 1/1836 of a proton or neutron.
The smallest part of an atom would be a quark. Quarks are either up or down quarks, and have virtually no mass. Neutrinos have even less mass, but are not part of an atom.
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.
It would be neutrons.
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.

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.

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.
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.
In the atom this particle is the electron. Generally in the particle physics: photons, gluons, neutrinos.
A positively charged particle in an atom is the proton. Protons are found in the nucleus of the atom along with neutrons, and they carry a positive charge equal in magnitude to the negative charge of the electron. The number of protons in the nucleus determines the atomic number of an element.
