1. Proton (p): The proton is the positively charged particle and is located in the nucleus. Its positive charge is of the same magnitude as that of the electron’s , negative charge.
2. Neutron (n): Neutron is inside the nucleus. The neutron does not have any charge. Except hydrogen (protium), the nuclei of all atoms contain neutrons.
3. Electron (e): This is a negatively charged particle. Electrons revolve around the nucleus of the atom in specific orbits. The mass of an electron is negligible as compared to that of a proton or neutron.
