Scientists Say: Rare earth element
Rare earth elements are so useful thanks to their electrons. Each atom of a rare earth element has a special group of electrons called f-electrons. These electrons can release energy in the form of very specific colors of light. Terbium, for instance, emits a precise color of green light. Meanwhile, europium can give off red or blue.
