8bet the Display:听As one of the noble gases, Krypton was chosen by the Instrumentation Center. The display box features a discharge tube in the shape of the element's symbol. The tube is filled with Krypton and powered by a transformer. When an electric charge excites the Krypton gas in the tube, the Krypton emits a greenish-yellow glow. The glow comes from an electron of the gas becoming excited from the energy. The excited electron leaves its electron shell and orbits the nucleus of the atom at a higher state. Eventually, the electron will return to its original state, releasing the extra energy as light.
