This element was discovered in 1898 by William Ramsey and Morris Travers, when traces of it remained after they had boiled off most of the other components of liquefied air. It was long thought to be inert, but is now known to form several compounds, the most stable involving fluorine. The spectral lines produced by this gas are orange and bright green, and in 1960, the orange-red wavelength of this element's isotope 86 was used to determine the length of the meter. FTP,
