Question

Find the number of emission lines, when the excited electron of Hydrogen atom in n = 6

drops to ground state, n = 1.
​

Answer 1

Explanation:

When the excited electron of an H atom in n = 6 drops to the ground state, the following transitions are possible:

The number of spectral lines:

n(n−1)/2

where n=6

Hence the total number of spectral line will be:

6×5/2 =15
