Question

The physical properties of isotopes of the same element are not identical. Give reasons.

Solution

Isotopes have different numbers of neutrons which affects the mass number. Mass number determines the physical properties such as boiling point, melting point, density etc.
Hence, physical properties of isotopes of the same element are not identical.
