Third excited state in hydrogen atom corresponds to n = 4. Hence maximum number of spectral lines, which can be emitted, is = n(n-1)/2 = 4(4-1)/2 = 6.

What is the maximum number of spectral lines emitted by a hydrogen atom when it is in the third excited state?

When a hydrogen atom is in the third excited state (n = 4), the maximum number of spectral lines is given by n(n−1)/2 . For n = 4, the number of lines is 4(4−1)/2 = 6.
