Bohr's second postulate implies quantisation of
- A Charge of an electron
- B Energy of an electron
- C Angular momentum of electron
- D Radiated energy by an electron
Answer & Solution
Correct Answer
(C) Angular momentum of electron
Step-by-step Solution
Detailed explanation
According to Bohr's second postulate, an electron can revolve only in those circular orbits where its angular momentum is an integral multiple of \(\dfrac{h}{2\pi}\).
Mathematically, \(L = mvr = \dfrac{nh}{2\pi}\), where \(n = 1, 2, 3, \dots\)
This postulate directly implies the quantisation of the angular momentum of an electron.
