Question

Assertion (A) : Isotopes of an element can be separated by using a mass spectrometer.
Reason (R) : Separation of isotopes is possible due to difference in electron number of isotopes.

• A. Both A and R are true and R is correct explanation of A
• B. Both A and R are true and R is not correct explanation of A
• C. A is true but R is false
• D. A is false but R is true

Answer 1

Answer: (C)

A is true but R is false

This is fact that isotopes can be separated using mass spectrometer and 2nd statement is false because in isotopes the number of neutrons differs not electrons.
