The theoretical magnetic moment of `Ti^(3+)` ion is ............. B.M.

Explanation

To find the theoretical magnetic moment of the `Ti^(3+)` ion, we will follow these steps:

### Step 1: Determine the Atomic Number and Electronic Configuration of Titanium
Titanium (Ti) has an atomic number of 22. The electronic configuration of Titanium is:
\[ \text{Ti: } [\text{Ar}] 3d^2 4s^2 \]

### Step 2: Determine the Electronic Configuration of `Ti^(3+)`
To find the electronic configuration of `Ti^(3+)`, we need to remove three electrons from the neutral Titanium atom. The electrons are removed first from the 4s orbital and then from the 3d orbital:
