The Bohr atomic model explains that when sodium and its compounds are under specific conditions, they emit a characteristic yellow light due to the movement of electrons. Here's an explanation of this phenomenon:
1. In the Bohr model, electrons move in specific energy levels or orbits around the nucleus of an atom.
2. When energy is absorbed by the sodium atoms, typically in the form of heat or electrical energy, the electrons in the atom get excited and jump to a higher energy level.
3. However, these excited electrons are unstable in the higher energy level and tend to return to their original lower energy level.
4. When the excited electrons transition back to their original energy level, they release the excess energy in the form of light.
5. In the case of sodium, this emitted light has a specific wavelength corresponding to the yellow color, which is a result of the energy released during the electron transition.
6. This characteristic yellow light emitted by sodium atoms when the excited electrons return to their original energy level is what creates the yellow color observed in sodium and its compounds under certain conditions.
In summary, the yellow light emitted by sodium and its compounds in specific conditions is a result of the movement of electrons between energy levels in the Bohr atomic model, where energy absorbed and then released by the electrons manifests as light with a specific wavelength, producing the yellow color.
