Elements with the general electronic configuration `(n-1)d^(3)ns^(2)` belong to which group in the modern periodic table ?

Explanation

To determine the group of elements with the general electronic configuration \((n-1)d^{3}ns^{2}\) in the modern periodic table, we can follow these steps:

### Step 1: Identify the Electronic Configuration
The given electronic configuration is \((n-1)d^{3}ns^{2}\). This means that the element has 3 electrons in the d subshell and 2 electrons in the s subshell of the outermost energy level.

### Step 2: Determine the Number of Electrons
From the configuration \((n-1)d^{3}ns^{2}\):
- The number of d electrons = 3
