MCQ
When $Z$ is doubled in an atom, which of the following statements are consistent with Bohr's theory?
- AEnergy of a state is doubled
- BRadius of an orbit is doubled
- ✓Velocity of electron in an orbit is doubled
- DEnergy of a state is halved
✓
Answer
Correct option: C.
Velocity of electron in an orbit is doubled
c
$\mathrm{E} \propto \mathrm{Z}^{2}$
$\mathrm{E} \propto \mathrm{Z}^{2}$
$\mathrm{R} \propto \frac{1}{\mathrm{Z}}$
$\mathrm{V} \propto \mathrm{Z}$
