Question
State the Bohr's postulate of angular momentum of an electron.
Solution
The angular momentum postulate proposed by Bohr argues that electrons can only rotate in orbits when their angular momentum is an integral multiple of `h/(2pi)` where h is Planck's universal constant.
Given an electron with mass 'm' and orbital velocity 'v', it can be explained using Bohr's postulate.
`mvr = (nh)/(2pi)`
Here n is an integer (n = 1, 2, 3.....) and is called the 'principal quantum number' of the orbit.
