Which of the following are the characteristics of isotopes of an element?
(i) Isotopes of an element have same atomic masses
(ii) Isotopes of an element have same atomic number
(iii) Isotopes of an element show same physical properties
(iv) Isotopes of an element show same chemical properties
(a) (i), (iii) and (iv)                         (b) (ii), (iii) and (iv)
(c) (ii) and (iii)                                  (d) (ii) and (iv)

Answers (1)

Ans (d)
Sol
Isotopes of an element are atoms with same atomic number and different atomic mass. Hence they have similar chemical properties as they have same electronic configuration and they have different physical properties due to different mass.

Hence option (d) is correct.
