The electronic configuration of a dipositive ion `M^(2+)` is 2, 8, 14 and its mass number is 56. The number of netrons present is

A

32

B

42

C

30

D

34

Text Solution

Verified by Experts

The correct Answer is:
C
The electrons in dipositive ion `(M^(12+))` is 2+8 +14 =24, Electrons = Protons in M = 26
`:.` Neutrons `= 56 -26 = 30`.
