Question

Describe Bohr's model of the atom.

Answer 1

In order to overcome the objections raised against Rutherford's Model of the atom, Neils Bohr put forward the following postulates about the model of the atom.
1. Only certain special orbits known as discrete orbits of electrons , are allowed inside the atom.

2. While revolving in discrete orbits the electrons do not radiate energy.

Answer 2

ANSWER.

The Danish physicist Neil's Bohr proposed the following postulates for reviting the Rutherford's model.
(a.) Atom has central nucleus surrounded by electrons.
(b.) An atom consists of small heavy positively charged nucleus in the centre and the electrons revolve around it, in paths called orbit or shells.
(c.) Each orbit has ficed energy, so these orbits are called energy levels or energy shells.
(d.) The order of the energy of these energy shells will be
K<L<M<N<O<........
or 1 <2 <3 <4 <5 <.........
(e.) As long as an electron remains in a particular orbit, it does not lose or gain energy.
(f.) Energy is neither absorbed nor emitted when electron is moving in an orbit. But energy is moving in an orbit. But energy is absorbed when it jumps from lower orbit to higher orbit to higher orbit. Whereas energy is emitted when it jumps from higher orbit to lower orbit.
