- Xenon is a chemical element with symbol Xe and atomic number 54 in the periodic table.
- It was discovered by William Ramsay in the year 1898.
- Xenon is a rare, colorless, odorless, tasteless and chemically unreactive gas.
- Xenon is a trace gas ( i.e., which makes up less than 1 % by volume of Earth’s atmosphere. It is found as a component in gases released from few mineral springs.
- It is also released as a by-product when the air is separated into Nitrogen and Oxygen.
- The element has an atomic number 54 as its nucleus contains 54 protons. It is available in all forms i.e., solids, liquids, and gases.
Optics and illumination
- It is used in Flash lamps called Xenon flash lamps.
- It is also used in Stroboscopic lamps and photographic flashes.
- Lasers are generated with the help of Xe gas.
- The element Xe acts as a natural anesthetic.
- Inhaling the mixture of oxygen and xenon produces a hormone which helps to increase Red Blood Cell (RBC) production.
- It is used to measure the flow of blood and also used to image the Brain, Heart, and Lungs.
- Also, the element is used in NMR spectroscopy
- The name Xenon is derived from a Greek word Xenos which means “stranger”.
- It is most expensive and most dense of all the gases.
- It produces a bluish purple color when electrified.
- It forms very good compounds with Fluorine.
