Structure of the Atom


All the Isotopes of an Element Have Identical Chemical Properties


The chemical properties of an atom of the element depend on the number of protons and electrons,not on the number of neutrons. Since all the isotopes of an element contain the same number of protons and electrons, therefore, the chemical properties of all the isotopes of an element are identical (or same).We can explain the identical chemical properties of all the isotopes of an element on the basis of their electronic configurations as follows.
All the isotopes of an element contain the same number of electrons because of which they have identical electronic configurations having the same number of valence electrons.Since all the isotopes of an element have identical electronic configurations containing the same number of valence electrons, therefore, all the isotopes of an element show identical chemical properties.For example,the two isotopes of chlorine,"Cl and J7CI, both have the same number of 17 electrons in them due to which both of them have the same electronic configuration of 2, 8, 7. Since both the isotopes of chlorine, Cl-35 and Cl-37, have identical electronic configurations (having the same number of 7 valence electrons), they show identical chemical properties.
