Question

Angular momentum of an electron is quantized.

(a) True

(b) False

I had been asked this question during an interview.

This question is from Bohr’s Model for Hydrogen Atom in division Structure of Atom of Chemistry – Class 11

Answer 1

The correct choice is (a) True

The best I can explain: According to Bohr’s postulate, angular momentum is quantized and this is given by the expression mevr = nh/2π. (n =1, 2, 3….).  mevr is the angular momentum and h is the Planck’s constant. Movement of an electron can only be possible in orbits whose angular momentum is the integral multiple of h/2π
