The evidence for the existence of krypton and xenon is, however, inconclusive.Astronomical Curiosities

That report was enough to make a man quit his job and go to Xenon to start a chicken ranch or grow oranges.
The animals on Xenon are immune from them, but when they land on a man, they send out tiny rootlets that are like minute hairs.
Aristarchus combated “the paradox of Xenon,” and it does not seem to have had much acceptance in antiquity.
The remaining elements of this group—neon, krypton, and xenon—have been obtained from liquid air.An Elementary Study of Chemistry
- a colourless odourless gaseous element occurring in trace amounts in air; formerly considered inert it is now known to form compounds and is used in radio valves, stroboscopic and bactericidal lamps, and bubble chambers. Symbol: Xe; atomic no: 54; atomic wt: 131.29; valency: 0; density: 5.887 kg/m³; melting pt: –111.76°C; boiling pt: –108.0°C
Word Origin for xenon
- A colorless, odorless, highly unreactive gaseous element found in minute quantities in the atmosphere and extracted commercially from liquefied air, used as an anesthetic and, in radioisotope form, for diagnostic imaging. Atomic number 54.
- A colorless, odorless element in the noble gas group occurring in extremely small amounts in the atmosphere. It was the first noble gas found to form compounds with other elements. Xenon is used in lamps that make intense flashes, such as strobe lights and flashbulbs for photography. Atomic number 54; atomic weight 131.29; melting point -111.9°C; boiling point -107.1°C; density (gas) 5.887 grams per liter; specific gravity (liquid) 3.52 (-109°C). See Periodic Table.
