Explanation:
Detailed explanation-1: -Tritium (3H) is the only radioactive isotope of hydrogen. The nucleus of a tritium atom consists of a proton and two neutrons. This contrasts with the nucleus of an ordinary hydrogen atom (which consists solely of a proton) and a deuterium atom (which consists of one proton and one neutron).
Detailed explanation-2: -Tritium is an isotope of hydrogen that is composed of one proton, two neutrons, and one electron.
Detailed explanation-3: -Hydrogen has no neutron, deuterium has one, and tritium has two neutrons. The isotopes of hydrogen have, respectively, mass numbers of one, two, and three.
