adioisotopes: What Are They and How Are They Made?What are isotopes?The isotopes of an element are all the atoms that have in their nucleus the number of protons (atomic number) corresponding to the chemical behavior of that element. However‚ the isotopes of a single element vary in the number of neutrons in their nuclei. Since they still have the same number of protons‚ all these isotopes of an element have identical chemical behavior. But since they have different numbers of neutrons‚ these isotopes
