How do neon lights work?

Neon signs are orange, like the word physics above. By definition, the atoms of inert gases such as helium, neon or argon never (well, almost never) form stable molecules by chemically bonding with other atoms. read more

Quick Answer. Neon lights work by applying high voltage to the electrodes at each end of a sealed glass tube filled with low-pressure neon gas. This ionizes the neon and causes it to glow. read more

A neon light consists of a glass tube filled with a small amount (low pressure) of neon gas. Neon is used because it is one of the noble gases. One characteristic of these elements is that each atom has a filled electron shell, so the atoms don't react with other atoms and it takes a lot of energy to remove an electron. read more
