In the atom:
Neutron:
Mass: 1,00866491600(43) amu.
Electron:
Mass: 5,4857990946(22)×10−4 amu.
Proton:
Mass: 1,007276466812(90) amu.
Both one proton and one neutron each has a relative mass of 1 a.m.u.
The neutron is a subatomic particle that has mass nearly equal to that of a proton but carries no electrical charge.
Electron, lightest stable subatomic particle known. It carries a negative charge, which is considered the basic unit of electric charge. The rest mass of the electron is 9.109 × 10−31 kg, which is only 1/1,840the mass of a proton. An electron is therefore considered nearly massless in comparison with a proton or a neutron, and the electron mass is not included in calculating the mass number of an atom.
no. ions are made of relatively whole atoms (plus or minus a few electrons)
The subatomic particle that fits this description is the electron. Electrons have a negative charge, are found outside of the nucleus in electron shells, and have a very small mass compared to protons and neutrons.
Both one proton and one neutron each has a relative mass of 1 a.m.u.
A neutron is the subatomic particle with a charge of 0 and a mass of 1 atomic mass unit.
The neutron is a subatomic particle that has mass nearly equal to that of a proton but carries no electrical charge.

No such particle exists. All particles with charge also have mass -- no exceptions. Every particle with zero mass also has zero charge -- no exceptions.
The neutron is the subatomic particle that has appreciable mass and lacks a charge.
The proton is the subatomic particle which carries the positive charge. It has a charge of +1 and a mass of 1,672 621 637(83).10-27 kg.
The tiny subatomic particle related to the electron that has no electric charge and little mass is the neutrino. Neutrinos are extremely difficult to detect due to their neutral charge and low interaction with matter.
It is a property, like mass. Not a particle. The electron and proton charges are considered to be the reference charges (-e and +e).
A electron is a subatomic particle outside the nucleus carrying a negative charge and very little mass. Other mass is negligible mass or a negative charge.
