Which are aspects covered by Bohr’s atomic model?
Electrons can have a measured radius.
Higher orbits have lower energies.
Electrons exist between orbits.
Electrons do not have energy, the energy is determined by the orbit.
Bohr’s atomic model covers the following aspects:
1. Quantized energy levels: Bohr proposed that electrons can only occupy specific energy levels or orbits around the nucleus. These energy levels are quantized, meaning that only certain values are allowed.
2. Stationary states: Electrons in Bohr’s model are considered to be in a stationary state when they occupy a specific energy level. They do not emit or absorb energy while in these stationary states.
3. Emission and absorption of energy: Electrons can transition between energy levels by either emitting energy (in the form of electromagnetic radiation) when moving to a lower energy level or absorbing energy to move to a higher energy level.
4. Conservation of angular momentum: Bohr's model explains that electrons in orbits have a fixed value of angular momentum, and during transitions between orbits, the total angular momentum of the electron and emitted or absorbed photon must be conserved.
5. No continuous emission spectrum: According to Bohr’s model, when an electron transitions between energy levels, it emits or absorbs energy as discrete packets or quanta, corresponding to the difference in energy between the two levels. This gives rise to a line spectrum rather than a continuous spectrum.
6. Limitations of the model: Bohr’s atomic model is limited to hydrogen-like atoms, which have only one electron. It does not fully explain the behavior of more complex atoms or the wave-like nature of electrons.
