The second member of the noble gases, highly inert. Widely used as a source of beautiful illumination when excited by an electric discharge.
 Discharge tube Discharge tube.
The glass tube bent into the shape of the letters "Ne" contains pure neon gas at very low pressure. When 6000v is applied to the tube, a low current of 20 mA or so causes the neon atoms to glow with a characteristic orange red light that is a familiar night time sight in every town and city. Comparing the brightness of the discharge with the other noble gases, you can see why neon is a popular choice.
