The octet rule refers to each atom’s desire or natural tendency to have 8 electrons on its valence shell by losing, acquiring, or sharing electrons. Similarly, fluorine has seven electrons on the outermost shell thus making the number of valence electrons of fluorine seven. Hence, the total number of valence electrons on xenon is eight. Xenon has eight electrons on the outermost shell. For the bond formation, they are either transferred or shared (in whole or in part). In the formation of a chemical bond, only the valence electrons are involved. Valence electrons refer to the total number of electrons present on an atom’s outermost shell. Thus, four fluorine atoms are bonded to a central xenon atom. It is because Xenon is less electronegative (2.6) than Fluorine (3.98) and we know the lesser the electronegativity value of an element the more likely it is to behave as a central atom. In this molecule, xenon acts as the central atom. There is one xenon atom and four fluorine atoms in a xenon tetrafluoride molecule as the name suggests. Xenon Tetrafluoride or Tetrafluoroxenon consists of two types of elements, Xenon and Fluorine. A dot represents a lone pair of electrons in a Lewis structure, while a straight line represents a bonded pair of electrons. The Lewis structure only considers the electrons in a molecule’s valence shell, ignoring the interior shells. The total number of lone and bound pairs of electrons in the atom is also shown in the Lewis structure. The Lewis structure, often known as the electron dot structure, is a diagrammatic representation of atom-to-atom bonding in a molecule. The melting and boiling point of xenon tetrafluoride is 117☌ and 115.7☌ respectively.It has a molar mass of 207.28 g/mol and a density of 4.04 g/cm 3.It reacts with water or moisture and gives off xenon, oxygen, hydrogen fluoride, and XeO 3.It is a stable solid at room temperature.It is a colorless solid with non-toxic properties.Xenon tetrafluoride is also used for research purposes as it contains xenon, an inert gas that does not readily react with other elements or compounds. It is found to react with silicone and form simple gaseous products, leaving behind a residue of metal impurities. Xenon tetrafluoride is used for identifying trace metal impurities in the Silicone rubber.

The hydrofluoric acid formed from the reaction of xenon tetrafluoride with water is highly corrosive and causes serious toxic health hazards if inhaled. When the solution is evaporated, a white, crystalline chemical known as Xenon (VI) oxide (XeO 3) remains. Xenon tetrafluoride reacts with water to give xenon, oxygen, hydrofluoric acid, and a very soluble species containing xenon. Xenon tetrafluoride is a strong oxidizing agent and is a highly toxic compound. Xenon Tetrafluoride or Tetrafluoroxenon (XeF 4) is a colorless chemical compound that exists in a solid state at room temperature.
