MCQ
According to Bohr hypothesis, discrete quantity is:
  • A
    Momentum
  • B
    Angular velocity
  • C
    Potential energy
  • D
    Angular momentum

Answer

  1. Angular momentum

Explanation:

Bohr's hypothesis

Electrons revolves round the nucleus in water orbits.

Orbit of the electron around the nucleus can take only some special values of radius.

The energy of the atom as a definite value in these orbits.

In this Orbits, Angular momentum (e) of the electron is integral multiple of the plank's constant h divided by 2n

$\text{i.e. l}=\text{n}\frac{\text{h}}{2\text{n}}.$
