MCQ
According to Bohr hypothesis, discrete quantity is:
- AMomentum
- BAngular velocity
- CPotential energy
- ✓Angular momentum
✓
Answer
Correct option: D.
Angular momentum
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 $2n$
$\text{i.e. l}=\text{n}\frac{\text{h}}{2\text{n}}.$
