Bohr's model of the atom unraveled the mystery of atomic spectra and explained the general chemical properties of the elements. It even led to the discovery of a new element called hafnium.

Bohr's atomic model explains the general structure of an atom. It consists of electrons orbiting a charged nucleus due to the Coulomb force in specific orbits having discretized energy levels.

(a) State Bohr's postulate to define stable orbits in hydrogen atom. How does de Broglie's hypothesis explain the stability of these orbits? (b) A hydrogen atom initially in the ground state …

Bohr’s theory was unable to explain the following observations : i) Bohr’s model could not explain the spectra of atoms containing more than one electron. ii) It could not explain the Zeeman …

Understand the wave-mechanical model of an atom by understanding atomic orbitals. Learn electron notation as a way to display electron configurations.

This model failed to explain Zeeman Effect and stark effect. Bohr model could not explain the uncertainty principle of Heisenberg. Bohr model was not related with classification and …

The Bohr's model explained stability of an atom by quantizing angular momentum.It explained discretes spectra of Hydrogen and we can calculate energy of nth orbit. Thus all options could …

Give the essential postulates of Bohr's model of an atom. How did it Explain i) the stability of an atom? ii) origin of spectral lines in the Hydrogen atom?

Bohr's model explained that in the center of an atom, a positively charged nucleus is present. Around the positively charged nucleus, electrons...

In Bohr's model of the hydrogen atom, it is a system consisting of a dense positively charged nucleus surrounded by orbiting electrons. The proposed atomic structure was similar to the …
