You need to understand convergence, production of UV, vis, IR, excitation, concentric energy levels and be able to draw the line spectra. If an electron falls from the 3-level to the 2-level, red light is seen. L'hydrogène est l'élément chimique de numéro atomique 1, de symbole H. L'hydrogène présent sur Terre est presque entièrement constitué de l'isotope 1H (un proton, zéro neutron) ; il comporte environ 0,01 % de 2H (un proton, un neutron). Bohr's model explains the spectral lines of the hydrogen atomic emission spectrum. This is the origin of the red line in the hydrogen spectrum. 11 Bohr’s model for H atom In 1913 Neils Bohr proposed a physical model to describe the spectrum of the hydrogen atom.

This series of lines is known as line or atomic spectrum of hydrogen. and so it can be expected to have the simplest spectrum. It is called spectral line. Preparation 1. The most prominent line was detected in 1853 by Anders Jonas Angstrom. The classification of the series by the Rydberg formula was important in the development of quantum mechanics. Hydrogen Spectrum. 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. The emission spectrum of atomic hydrogen is given by this amazing spectral series diagram:. While the electron of the atom remains in the ground state, its energy is unchanged. The convention is to name states s'', states p'', states d'', and states f''. The first excited state of Hydrogen has . He gave the spectrum of Hydrogen ion which has one electron only, so this spectrum cannot be applied for atoms with more than one electron.
