What is Xenon?
- 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.
Physical properties of Xenon
- Xenon is a rare, colourless, odourless, 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.
Applications and effects of Xenon
Optics and illumination
- It is used in Flash lamps called Xenon flashlamps.
- 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 anaesthetic.
- 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
Interesting Facts of Xenon
- 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 colour when electrified.
- It forms very good compounds with Fluorine.
