postulates of Bohr's atomic model :
According to Bohr's theory , electrons revolve in definite circular orbits around the nucleus and these orbits are designated by the letters K, L, M, N or by the numbers 1, 2 ,3, 4 and so on.
As long as the electrons revolve in a particular orbit they can neither gain energy nor loose energy. Such orbits are called as stationary orbits or stationary states.
When an electron jumps from an higher orbit to a lower orbit it releases energy in the form of raldiations and when an electron jumps from lower orbit to a higher orbit it absorbs energy in the form of raldiations.
The angular momentum of aln electron is an integral multiple of h/ 2π mvr = nh/ 2π
It explains the stability of an atom and also the line spectrum of hydrogen atom

Electrons revolve around the nucleus in a fixed circular path termed “orbits” or “shells” or “energy level.”The orbits are termed as “stationary orbit.”Every circular orbit will have a certain amount of fixed energy and these circular orbits were termed orbital shells. The electrons will not radiate energy as long as they continue to revolve around the nucleus in the fixed orbital shells.The different energy levels are denoted by integers such as n=1 or n=2 or n=3 and so on. These are called as quantum numbers. The range of quantum number may vary and begin from the lowest energy level (nucleus side n=1) to highest energy level. Learn the concept of an Atomic number here.The different energy levels or orbits are represented in two ways such as 1, 2, 3, 4… or K, L, M, N….. shells. The lowest energy level of the electron is called the ground state. Learn the concept of Valency here in detail.The change in energy occurs when the electrons jump from one energy level to other. In an atom, the electrons move from lower to higher energy level by acquiring the required energy. However, when an electron loses energy it moves from higher to lower energy level.
