Noble gases are elements under the last column or group of the periodic table. Since their outermost electron shells contain a full complement of electrons, noble gases are inert or nonreactive. Fluorescent lights and neon signs often use tubes filled with noble gases with the exception of radon, which is radioactive and thus dangerous to handle. The color of the light depends on the type of gas and the type of coating. Neon Neon is the 10th element of the periodic table and the most inert of the noble gases. Once widely used in advertising signs and displays, it gave its name to neon signs. All neon signs don’t use neon, but the first neon signs did. In the absence of a phosphor coating on the tube, neon glows an orange color wh
