MCQ
The Bohr model of atoms
- ✓Assumes that the angular momentum of electrons is quantized
- BUses Einstein’s photo-electric equation
- CPredicts continuous emission spectra for atoms
- DPredicts the same emission spectra for all types of atoms
In these orbits, angular momentum of electron can have magnitude as
$\frac{h}{2 \pi^{\prime}} \frac{2 h}{2 \pi^{\prime}} \frac{3 h}{2 \pi} \cdots \cdots \cdot$ etc $,$ but never as $\frac{1.5 h}{2 \pi^{\prime}}, \frac{2.5 h}{2 \pi^{\prime}}, \frac{3.5 h}{2 \pi} . \ldots . . .$ etc.
This is called the quantisation of angular momentum.
