Explain Bohr's model of an atom.
Answers
Neils Bohr gave atomic model in 1913.The main points of this model are:
1) An atom consists of a central positive part called the nucleus which contains all the protons and neutrons.
2) Electrons which are present outside the nucleus revolve around the nucleus in definite circular paths called orbits or shells.
3) Each orbit has a fixed energy and the orbitals are represented by the symbols K, L,M, N etc or by the numbers 1,2,3 …
4) Each orbit can accommodate not more than a fixed number of electrons.
5) Electrons moving in the same orbit donot lose or gain energy.
6) Electrons lose energy on jumping from a higher orbit to lower one and vice-versa.

Main Points of the Bohr Model
Electrons orbit the nucleus in orbits that have a set size and energy.
The energy of the orbit is related to its size. The lowest energy is found in the smallest orbit.
Radiation is absorbed or emitted when an electron moves from one orbit to another.
