Isotopes of the same element have similar chemical properties because they have the same number of
nuclides
protons
neutrons
atoms

Isotopes differ in the number of neutrons in their nucleus, but they have the same number of protons (which determines the number of electrons). Since chemical properties are primarily determined by the electron configuration, isotopes of the same element behave similarly in chemical reactions.
