Absorption and Emission of Radiation
What you need to know
Recall that the precise arrangement of electrons within atoms shifts when they absorb or emit electromagnetic radiation.
Explain how electrons jump to higher energy levels upon gaining energy from heat, electricity, or radiation, and emit electromagnetic radiation when dropping back to lower levels.
Understand that the specific frequency of the emitted radiation correlates with the exact size of the energy jump within the atomic model.
Utilize the energy level model of the atom to explain phenomena such as the visible light emitted by sodium or the ultraviolet light emitted by mercury.
