• A. Protons are present in the nucleus
• B. Electrons are revolving around the nucleus
• C. Centrifugal force produced due to the revolving electrons balances the force of attraction between the electron and the protons
• D. Angular momentum of electron is an integral multiple of $\frac{h}{2\pi}$

Answer 1

Answer: (D)

Angular momentum of electron is an integral multiple of $\frac{h}{2\pi}$

Answer 2

The electron can move only in these circular orbits where the angular momentum is a whole number multiple of $\frac{h}{2\pi}$ or it is quantised.
