Vedclass · Answer

(A) Isotopes are defined as atoms of the same element that have the same atomic number $(Z)$ but different mass numbers $(A)$.Since the atomic number $(Z)$ represents the number of protons,isotopes have the same number of protons.The mass number $(A)$ is the sum of protons $(Z)$ and neutrons $(N)$,so $A = Z + N$.Because the mass number $(A)$ differs while the atomic number $(Z)$ remains the same,the number of neutrons $(N = A - Z)$ must be different for isotopes.Therefore,option $A$ is correct.
