Question

Explanation of niel Bohr's model shortly 3 points

Answer 1

A Danish physicist named Neil Bohr in 1913 proposed the Bohr atomic model. He modified the problems and limitations associated with Rutherford’s model of an atom.

1. Bohr atomic model and the models after that explain the properties of atomic electrons on the basis of certain allowed possible values.
2. The model explained how an atom absorb or emit radiation when electrons on subatomic level jump between the allowed and stationary states.
3. German-born physicists James Franck and Gustav Hertz obtained the experimental evidence of the presence of these states.

Earlier in Rutherford Model, Rutherford explained in an atom a nucleus is positively charged and is surrounded by electrons (negatively charged particles).

Answer 2

Answer:

Bohr proposed that electrons do not radiate energy as they orbit the nucleus, but exist in states of constant energy which he called stationary states. This means that the electrons orbit at fixed distances from the nucleus (see below). Bohr's work was primarily based on the emission spectra of hydrogen.
