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.

physical properties are related with nucleus of an atom and chemical properties are related with the number of protons in the nucleus.is this statement is correct?

No, this is not correct.

Chemical properties are determined by the outer shell electrons.
Physical properties are determined by the interparticular forces in the bulk substance.

This is a simplification, but useful.

Could I say because they have same atomic number but different mass number

Isotopes have same chemical properties due to same electronic configuration but physical propertise is different due to mass number
