Which of the following ion has magnetic moment is 3.87 BM :-

Options

A. `Ti^(3+)`
B. `Sc^(+)`
C. `Ti^(+)`
D. `Mn^(+5)`

Explanation

To determine which ion has a magnetic moment of 3.87 BM, we can follow these steps:

### Step 1: Understand the Formula for Magnetic Moment
The magnetic moment (μ) can be calculated using the formula:
\[ \mu = \sqrt{n(n + 2)} \]
where \( n \) is the number of unpaired electrons.
