Question

Describe Bohr's model of the atom.

Accepted Answer

In order to overcome the objections raised against Rutherford's model of the atom, Neil’s Bohr put forward his model of the atom. According to Bohr's model of the atom,
An atom consists of a small positively charged nucleus at its centre.

The whole mass of the atom is concentrated at the nucleus.

The volume of the nucleus is smaller than the volume of the atom (by a ratio of about $1 : 105$ ).

The protons and neutrons of the atom are present in the nucleus.

The electrons of the atom, which are negatively charged, revolve around the nucleus in definite circular paths known as orbits or which are designated as $K, L, M, N$ etc. or numbered as (n) = $1, 2, 3, 4$ etc. (outward from the nucleus).

As each orbit is associated with a fixed amount of energy, these orbits are also known as energy levels. While revolving in discrete orbits, the electrons do not radiate energy. When an electron jumps from one energy level to another, the energy of the atom changes.
