Isotopes are two or more atoms that have the same number of protons (ie they are from the same element), but different numbers of neutrons.[1] For example, the most common isotope of hydrogen has a single proton and no neutrons in its nucleus. A very small proportion of hydrogen atoms are of the isotope deuterium (with one proton and one neutron)[2] or tritium (with one proton and two neutrons)[3].
