are able to use these radioisotopes is study the chemistry of cells because these atoms have the same chemical properties as the not stoms. Why are the chemical properties of all isotopes of the same cloment identical? __

The chemical properties of all isotopes of the same element are identical because they have the same number of protons and electrons. The number of protons determines the element, and the number of electrons, when equal to the number of protons, makes the atom neutral. Isotopes differ only in the number of neutrons, which affects the atomic mass but not the chemical behavior. This is why isotopes of the same element can be used to study the chemistry of cells without altering the chemical properties of the element.
