For the metallic salts used in the flame tests, which put out light with the highest energy? Explain why based on the Bohr model.

 

Answer:

The Bohr model says that electrons exist only at certain allowed energy levels. When you heat an atom, some of its electrons are "excited* to higher energy levels. When an electron drops from one level to a lower energy level, it emits a quantum of energy. The wavelength (colour) of the light depends on the difference in the two energy levels.
