Explanation

Atoms consist of three main subatomic particles: protons and neutrons in the nucleus, and electrons orbiting around the nucleus. Ions are atoms with a charge, not basic components. Neutrinos are elementary particles but not part of atoms. Protium, deuterium, and tritium are isotopes of hydrogen, not basic components.
