Facts about xenon
Here are a few interesting facts about xenon element.
- Xenon was given its name from the Greek word “xenos” which means stranger.
- Xenon gas is 4 times heavier than air.
- Xenon is very rarely available and so it is a very expensive noble gas.
- The concentration of xenon in the earth’s atmosphere is only 1 part per 20 million.
- Mars’s atmosphere also contains xenon in the concentration of 0.08 ppm.
Properties of xenon
Here is a list of some physical properties and chemical properties of xenon.
Physical properties of xenon
- Xenon is a colorless, odorless and tasteless gas.
- The solidified xenon gas appears light blue in color.
- Xenon has FCC crystal structure.
- Xenon glows with blue (or lavender) light when it is subjected to electrical discharge.
- The melting point and boiling point of xenon is -111.7 °C and -108 °C respectively.
Chemical properties of xenon
- Xenon has 8 valence electrons and this indicates that it has a stable octet.
- The electron configuration of xenon is [Kr] 4d10 5s2 5p6 and the electron shell arrangement is 2, 8, 18, 18, 8.
- Xenon is chemically inert but it shows a chemical reaction with some highly reactive elements like fluorine.
Uses of xenon
Here are some uses of the xenon element.
- Xenon is used in flash lamps as well as stroboscopic lamps because it gives a blue or lavender light on electrical discharge.
- Xenon is also used as an anesthetic gas in medical applications.
- Xenon gas is also used in TV tubes.
- Xenon is also used in headlights of vehicles (which gives a bluish glow).
