The hydrogen atom is said to be stable when the electron present in it revolves around the nucleus in the first orbit having the principal quantum number n = 1. Spectrum of Hydrogen is an important piece of evidence to show the quantized electronic structure of an atom. The following are the series in the hydrogen spectrum: – a) Lyman Series: – when the electron jumps from any higher stationary orbit to first stationary orbit, the spectral lines falls in the Lyman series. Academic year. The emission spectrum of atomic hydrogen is given by this amazing spectral series diagram:. Transcript and Presenter's Notes.
