If the value of `n +1 = 7` then what should be the increasing order of energy of the posible sub-shells ?

Options

A. `4f lt 5d lt 4p lt 7s`
B. `7s lt 6p lt 5d lt 4f`
C. `7s lt 6p lt 5d lt 4p`
D. `4flt 5d lt 6p lt 7s`

Explanation

To solve the question, we need to determine the increasing order of energy of the possible subshells when given that \( n + 1 = 7 \). Here's a step-by-step solution:

### Step 1: Determine the value of \( n \)
Given the equation \( n + 1 = 7 \), we can find \( n \) by rearranging the equation:
\[ n = 7 - 1 = 6 \]
