The magnetic moment of `M^(x+)` (atomic number `= 25` is ` sqrt(15) BM` .The number of unpaired electron and the value of x respectively are

Options

A. 4,3
B. 3,4
C. 3,2
D. 5,2

Explanation

To solve the problem, we need to find the number of unpaired electrons and the value of x for the ion \( M^{x+} \) with an atomic number of 25, given that its magnetic moment is \( \sqrt{15} \) Bohr Magnetons (BM).

### Step-by-Step Solution:

1. **Understanding the Magnetic Moment Formula:**
The magnetic moment (\( \mu \)) in Bohr Magnetons is given by the formula:
\[
\mu = \sqrt{n(n + 2)}
