Neon was discovered in 1898 alongside krypton and xenon, identified as one of the three remaining rare inert elements in dry air after the removal of nitrogen, oxygen, argon, and carbon dioxide. Its discovery was marked by the distinctive bright red emission spectrum it exhibited, leading to its immediate recognition as a new element.

Neon was discovered (1898) by the British chemists Sir William Ramsay and Morris W. Travers as a component of the most volatile fraction of liquefied crude argon obtained from air. It was immediately recognized as a new element by its unique glow when electrically stimulated.

Neon was discovered in 1898, in London, by British chemists Morris W. Travers and Sir William Ramsay. Ramsay discovered it by chilling an air sample until it became a liquid then capturing the gases released from the liquid as it was warmed.
Two British scientists, Sir William Ramsay and Morris Travers, discovered neon, argon, krypton, and xenon. Together they discovered a brand new gas element in 1898. Four years before, Ramsay, a physical chemist, had found argon and was the first person to isolate helium in 1895.
