Bohr's second postulate implies quantisation of

Options

  1. ACharge of an electron
  2. BEnergy of an electron
  3. CAngular momentum of electron
  4. DRadiated energy by an electron

Correct answer

C. Angular momentum of electron

Step-by-step solution

According to Bohr's second postulate, an electron can revolve only in those circular orbits where its angular momentum is an integral multiple of h 2 . Mathematically, L = mvr = nh 2 , where n = 1, 2, 3, This postulate directly implies the quantisation of the angular momentum of an electron. Answer: Angular momentum of electron
