What is bohrs postulates?

Answer 1

1. Electrons orbit the nucleus. They are held in orbit by an electrostatic force.
2. Electrons can only be in certain, permitted orbits and an electron does not emit radiation when it is in one of these orbits.
3. An electron only emits radiation when it "falls" from a higher energy state to a lower state.
4. The radii of the allowed orbits are also quantized - each energy state has a specific radius proportional to h/2Ï€.

5.Angular momentum of electron will be mvr = nh/2Ï€,n is principle quantum no.

Answer 2

Bohr's postulates are a set of rules that describe the behavior of electrons in an atom. They include the idea that electrons orbit the nucleus in specific energy levels, that electrons emit or absorb energy when they move between levels, and that the angular momentum of an electron is quantized. These postulates help explain the structure of the atom and the emission spectra of elements.
