Which of the following is true for Bohr's model?
An electron can move only in those orbits for which its angular momentum is an integral multiple of
Electrons revolve around nucleus in discrete and quantized energy levels/orbits.
The energy of an electron in the orbit do not change with time.
Electron will move from a lower stationary state to a higher stationary state when required amount of energy is absorbed.
The main postulates of Bohr's theory were:
a. Electrons only rotate in certain selected or permissible orbits.
b. As long as the electrons move in these orbits, they neither absorb or release energy.
c. The electron will move from a lower stationary state to a higher stationary state when the required amount of energy is absorbed by the electron. When the electron jumps back to the lower energy level, it emits the same amount of energy. The energy change does not take place in a continuous manner.
