explain the postulate of Bohr's model of atom. how does the this model of atom explain the stability of the atom?
Answers
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.It explains the stability of an atom and also the line spectrum of hydrogen atom.

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
