Vedclass · Answer

(D) Isotopes of an element have the same number of electrons and protons, but they differ in the number of neutrons, which leads to a difference in their atomic masses.Because of this difference in atomic mass, isotopes can be separated using a mass spectrometer, which separates ions based on their mass-to-charge ratio $(m/q)$.Since the Assertion claims that separation is due to the difference in electron numbers, the Assertion is incorrect.However, the Reason stating that isotopes can be separated by a mass spectrometer is correct.Therefore, the correct option is $D$.

Assertion: Separation of isotopes is possible because of the difference in electron numbers of isotopes.
Reason: Isotopes of an element can be separated by using a mass spectrometer.
