On the basis of crystal field theory. Write the electronic confirguration of `d^(6)` in terms of `t_(2g) " and " e_(g)` in an octahedral field when `D_(0) lt P.`

Explanation

To solve the problem of writing the electronic configuration of \( d^6 \) in terms of \( t_{2g} \) and \( e_g \) in an octahedral field when \( \Delta_0 < P \) (where \( \Delta_0 \) is the splitting energy and \( P \) is the pairing energy), we will follow these steps:

### Step 1: Understand the Crystal Field Splitting
In an octahedral field, the five d-orbitals split into two sets:
- \( t_{2g} \) (lower energy, consisting of three orbitals)
- \( e_g \) (higher energy, consisting of two orbitals)

### Step 2: Determine the Filling Order
