Neon (atomic number 10, symbol Ne) is a chemical element and an inert noble gas, which gives a red-orange glow to neon advertising signs, low-voltage glow lamps, and high-voltage discharge tubes.
This element is the 2nd lightest noble gas, with the narrowest liquid range of all elements. It has 3 times the refrigerating capacity of liquid hydrogen and 40 times that of liquid helium. Neon is a less expensive refrigerant compared to helium. Two types of lighting are made neon glow lamps and signs. Neon lamps are used in circuit-testing equipment and as power-on indicators. Today, LEDs or light-emitting diodes...Read More
