Question

describe Bohr's model of the atom​

Answer 1

Answer:

Unlike earlier models, the Bohr Model explains the Rydberg formula for the spectral emission lines of atomic hydrogen. The Bohr Model is a planetary model in which the negatively-charged electrons orbit a small, positively-charged nucleus similar to the planets orbiting the Sun (except that the orbits are not planar).

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.
