Explanation:

The atom consists of three subatomic particles:

- The proton: protons are inside the nucleus of the atoms, they have positive charge of +e (), and a mass of approximately

- The neutron: neutrons are also located inside the nucleus of the atoms, they have no electrical charge and mass similar to the mass of the proton

- The electron: electrons orbit around the nucleus in a cloud, they have negative charge of -e (), and their mass is about 1800 time smaller than the mass of the proton ()
