13.Nuclei
easy
Assertion: Separation of isotope is possible because of the difference in electron numbers of isotope.
Reason: Isotope of an element can be separated by using a mass spectrometer
A
If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
B
If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
C
If the Assertion is correct but Reason is incorrect.
D
