Explain Bohr's model of atom.
Answers
Explanation:
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:
According to Bohr’s theory:
The atom consists of a small positively charged nucleus at its centre and surrounded by negatively charged electrons in a definite circular path.
The nucleus contains all the protons and neutrons of the atom.
The electrons of the atom revolve around the nucleus in definite circular paths known as orbits which are designated as K, L, M, N or numbered as n=1,2,3,4 outward from the nucleus. The orbits are also known as stationary orbits.
Each orbit is associated with a fixed amount of energy. The lowest energy level of the electron is called the ground state. Therefore, these orbits are also known as energy levels or energy shells.
