Question

The chemical properties of isotopes are identical, why

Answer 1

However they have different numbers of neutrons, which affects the mass number. Mass number determines the physical properties such as boiling/melting/density etc. They have similar chemical properties becauseisotopes of an element have the samenumber of electrons as an atom of that element.

Answer 2

because they have same atomic no thus they have same valency , so same chemical properties
