Question

State True or False.

The angular momentum of electron in a shell is quantized, was derived by Bohr.

• A. True
• B. False

Answer 1

The correct option is B False

Bohr's postulates:
Of the finite number of circular orbits possible around the nucleus, and electron can revolve only in those orbits whose angular momentum (mvr) is an integral multiple of factor $h/2\pi$. And it was derived by de-Broglie.
