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.
Medicine
- 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.
XeF4 and XeF6 are expected to be
XeF4 oxidizes potassium iodide
XeF4 + 4I– → 2I2 + 4F– + Xe
XeF4 and XeF6 are expected to be oxidizing because in both the reactions XeF4 and XeF6 both caused the oxidation. XeF6 oxidizes hydrogen like other xenon fluorides.
Frequently Asked Questions – FAQs
What is geometry of XeF4?
The shape of XeF4 is square planar. The central Xe atom has 4 bond pairs of electrons and two lone pairs of electrons. It undergoes sp3d2 hybridization which results in octahedral electron geometry and square planar molecular geometry. The two lone pairs are at opposite corners of an octahedron.
What is XeF4 used for?
XeF4 is a compound that normally occurs as a colorless/white, crystalline solid. This compound is made of up xenon (a noble gas) and fluoride (a naturally occurring mineral). XeF4 can be used to help find and analyze trace metals that contaminate silicone rubber.
Is Xe element a metal?
Xenon (Xe) exists as a colourless, odourless gas and is chemically inert. It has the atomic number 54 in the periodic table and belongs in Group 18, the Noble Gases. It is a non metal with the symbol Xe. Xenon was discovered in 1898 by William Ramsay and Morris Travers.
What are some characteristics of xenon?
Xenon is one of the inert or noble gases and is odorless, colorless, tasteless and chemically non-reactive. While not toxic on its own, its compounds are strong oxidizing agents that are highly toxic.
Xenon hexafluoride has a distorted octahedral geometry. Due to the presence of one lone pair on a xenon atom, the octahedral geometry is distorted.
