Question
Physics Question on Nuclei
Isotopes of an element can be separated by using a mass spectrometer. Separation of isotopes is possible because of the difference in electron numbers of isotopes.
A
If both A and R are true, and R is a correct explanation of the A
B
If both A and R are true, but R is not a correct explanation of the A
C
If A is true, but R is false
D
If both A and R are false
Answer
