HELLO MATE !!!
YOUR ANSWER IS,
20.
This can be calculated using simple formula.
[n2 - n1] [n2 - n1 + 1]
where,
n2 =higher shell from where electron makes transition.
n1 = lower energy shell.
4 × 5
= 20

The total number of spectral lines when an electron jumps from the 8th orbit to the 2nd orbit is 21.
Given:
Electron jumps from 8th orbit to 2nd orbit
n₁ = 8
n₂ = 2
To find:
The total number of spectral lines.
Solution:
n₁ = 8, n₂ = 2
The total number of the spectral line is given by the equation:
N = (n₂ - n₁) (n₂ - n₁ + 1)/2
So,
N = (8 - 2) (8 - 2 + 1)/2
N = 6 × 7/2
N = 42/2
N = 21
The total number of spectral lines is 21.
