Question

a) Physical properties of Isstobes are different give reason​

Answer 1

Answer:

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

Answer 2

Answer:

since isotopes have same electronic configuration therefore they have same chemical properties

but the have different mass number, and the physical properties depends upon the mass number. That's the reason why isotopes have same chemical properties but different physical properties
