Atomic number and mass number of an element `M` are `25` and `52` respectively. The number of electrons, protons and neutrons in `M^(+2)` ion are respectively.

Options

A. `25,24` and `27`
B. `25,27` and `25`
C. `27,25` and `27`
D. `23,25` and `27`

Answer

D

Explanation

(d) `._25^52 M^(2 +) , Z = 25 = p, e = 25 - 2 = 23`
`A = 52`
`n = A - Z = 52 - 25 = 27`.
