Question

what is the value of angular momentum for nth Bohr Orbit​

Answer 1

The angular momentum of the nth orbit is :

 mvr = $\frac{nh}{2\pi }$

where,  m =  mass of the electron

             v =  velocity of the electron

             r = radius of the orbit

             n = orbit or any natural number

             h = plank's constant = 6.67 ×$10^{-34}$ j/sec

• According to Bohr's model, electrons can revolve only in those orbits whose angular momentum is an integral multiple of $\frac{h}{2\pi }$.
• These electrons revolve in permitted circular orbits who contains certain amount of energy.
