Neon is the second lightest noble gas, after helium, and it has an atomic number of 10. On the periodic table, it is identified with the symbol Ne. The noble gases were recognized in the late 1800s, when scientists realized that an entire class of gases was missing from the periodic table of elements.
This time, they found the gas that perches above argon on the Periodic Table: neon. The most common use of neon is in neon signs, which have a century-long history. First developed by French engineer Georges Claude in 1902, neon lights create light by applying electricity to neon or argon in a sealed glass tube.
