Question

why do isotopes of an element show similar chemical properties

Answer 2

hello friend
 They have similar chemical properties because isotopes of an element have the same number of electrons as an atom of that element. The electron arrangement is the same owing to same chemical properties. However they have different numbers of neutrons, which affects the mass number.
