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.
