Postulates of Bohr Atomic Model

The foundations of quantum mechanics were laid by Niels Bohr, and they are as follows:

• The electrons in the hydrogen atom spin around in stable orbits, generating no radiant energy.
• The angular momentum in stationary orbits is a multiple of the equation h / 2,π and L = n h / 2π, where n is known as the quantum number.
• The electron changes from a non-radiating orbit to a lower-energy orbit. When this occurs, a photon with the same energy as the difference between the final and beginning states is emitted. hv= E_i E_f is used to calculate frequency (v).

Atomic Spectra is the spectrum of radiation of electromagnetic waves produced due to the transition of an electron from one energy level to another level within an atom. Atoms have an equal number of negative and positive charges. Atoms were described as spherical clouds of positive charges with embedded electrons in Thomson’s concept. In Rutherford’s model, one tiny nucleus carries the majority of the atom’s mass, as well as its positive charges, and the electrons orbit it.

Every element’s atoms have their own unique spectra and are stable. The spectrum is made up of line spectrums, which are parallel lines that are isolated. In this article, we will learn atomic spectra, its definition, and more in detail.
