Argon, krypton and xenon are very unreactive. They replace the air inside the lamp, preventing the metal wire from burning away.

Like all noble gases, xenon is ... isolated argon in 1894. Remarkably, Ramsey then went on to isolate helium (1895) and radon (1908) and, with Morris Travers, to discover krypton, neon and xenon ...

This is not surprising since xenon is by far the least abundant of the noble gases in the atmosphere: by volume, about 1 per cent of the air is argon, 18 parts per million neon, 5 ppm helium, 1 ppm ...

The six naturally occurring noble gases are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and the radioactive radon (Rn). Oganesson (Og) is a synthetically produced highly radioactive ...

Abstract: The arc emission spectra of two identical high-pressure dc capillary lamps (one with 2 atmospheres xenon, one with 2 atmospheres krypton) are measured and compared. The total efficiency, as ...

The gases commonly consist of an inert gas such as argon, krypton or xenon, and a reactive gas such as fluorine or chlorine. When electrically excited, the gas mixture temporarily forms excited ...

Fast forward to 2025: xenon, an odourless noble gas in Group 18 of the periodic table, is now offering hope for Alzheimer’s ...

For example, such as data on the noble gases argon, krypton, and xenon, on the likely wall material tungsten, and on other possible impurities. Much of the work in this CRP focused on possible ...
