Explanation: Using the isotopes of Hydrogen for example, protium , mass number=1, atomic number=1 has one electron and a proton. Deuterium, mass number=2, atomic number= 1, has one electron and one proton and one neutron, Tritium, mass number=3, atomic number =1, has one electron, one proton and two neutron. Hydrogen exists as a diatomic molecule to have two electrons in its orbitals to achieve stability. The proton however remains the same number for each participating atom of the molecule.
