# What is the Maximum Number of Emission Lines When the Excited Electron of an H Atom in N = 6 Drops to the Ground State? - Chemistry

What is the maximum number of emission lines when the excited electron of an H atom in n = 6 drops to the ground state?

#### Solution

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

Hence, a total number of (5 + 4 + 3 + 2 + 1) 15 lines will be obtained in the emission spectrum.

The number of spectral lines produced when an electron in the nth level drops down to the ground state is given by (n(n-1))/2

Given,

n = 6

Number of spectral lines = (6(6-1))/2 = 15

Is there an error in this question or solution?
