Shortcoming of Bohr Theory Despite the fact of direction which Bohr explain that give us general information about atom, theory still have some questionable assumption, which is called shortcoming of Bohr theory; Bohr Theory did not explain the atomic spectra

4th Postulate hydrogen spectrum  In other to modify one orbit to another, electron must either emit or absorb energy which is proportional to the distance between the two orbits. Introduction of light energy bring about photon with a wavelength given

3rd Postulate: As a consequence of the restrictions on the angular momentum of an orbit, the energy of an electron in a given orbit is constant. As long as the electron stays in that orbit, it neither absorbs nor radiates

2nd Postulate Read full text on 1st Bohr Postulate In the first postulate we refer to orbit to be in circular for, and they harbor electron. But it should interest you to know that not all circular orbit allowed electron.

Postulate of Bohr Theory The fact that hydrogen spectrum of Balmer equation was represented successfully, but there were no theoretical proved for it. Therefore, Niels Bohr in 1914 provide a theory that explain the genesis of it spectrum. The theory

Atomic Spectra When atom absorbed quantum energy, it move to an excited state opposing it ground state. When this atom loose or emitted the absorb energy or light, it will return to ground state. In this tutorial we going to

Excitation and De-excitation Atom has the power of transition between the orbits which is permitted by quantum mechanics, the transition take place by either absorbing or emitting equal difference energy between the orbits. Excitation take place as a result of

Atomic Composition Atom consist of varieties of structure, the varieties structure of atom determines it chemical and physical properties composition it is made up of. In the early discovery of atom, there structural varieties was not known until the discovery
