Question

What is the reason for the identical chemical properties of all the isotopes of an element ? Explain with the help of an example.

Answer 1

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. Mass number determines the physical properties such as boiling/melting/density etc.
