Question

What is bohr's model?​

Answer 1

In atomic physics, the Bohr model or Rutherford–Bohr model, presented by Niels Bohr and Ernest Rutherford in 1913, is a system consisting of a small, dense nucleus surrounded by orbiting electrons—similar to the structure of the Solar System, but with attraction provided by electrostatic forces in place of gravity.

Answer 2

BOHR'S MODEL OF ATOM :

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 an atom:

• (i) Only certain special orbits known as discrete orbits of electrons, are allowed inside the atom.
• (ii) While revolving in discrete orbits the electrons do not radiate energy.

These orbits or shells are called energy levels. Energy levels in an atom are shown in Fig.

There orbis for shells are represented by the letters K,L,M,N... or the number n = 1,2,3,4...

ABOUT BOHR :

Neils Bohr (1885-1962) was born in Copenhagen on 7 October 1885. He was appointed professor of physics at Copenhagen University in 1916. He got the Nobel prize for his work on the structure of atom in 1922. Among Professor Bohr's numerous writings. three appearing

s books are:

• (i) The Theory of Spectra and Atomic
• Constitution.
• (ii) Atomic Theory and.
• (iii) The Description of Nature
