Question
What did Bohr’s atomic model explain?
- Stability of atom
- Origin of line spectrum of hydrogen
- Arrangement of electrons
- All the above
Hint:
Bohr's model explained the stability of atoms, the origin of line spectrum of hydrogen, and arrangement of electrons.
The correct answer is: All the above
- Bohr stated that the electrons move stably in orbits with fixed size and energy
- The electrons will be more stable when they are in the lowest form of energy as there is no more orbit to fall.
- Bohr's model is applicable for a few atoms which have one or two electrons.
- So he explained the hydrogen origin of the line spectrum.
