Xenon tetrafluoride, XeF4, is one of the chemical compounds derived from the noble gas xenon. The boiling point of a liquid is the temperature at which the Vapor pressure of the liquid equals the environmental pressure surrounding the liquid The term coordination geometry is used in a number of related fields of chemistry and solid state chemistry/physics Molecular geometry or molecular structure is the three- Dimensional arrangement of the Atoms that constitute a Molecule. The square planar molecular geometry in Chemistry describes the stereochemistry (spatial arrangement of atoms that is adopted by certain Chemical compounds As In physics there are two kinds of dipoles ( Hellènic: di(s- = two- and pòla = pivot hinge An electric dipole is a The debye (symbol D) is a non- SI, CGS unit of electrical dipole moment. The flash point of a flammable liquid is the lowest Temperature at which it can form an ignitable mixture in air In Chemistry, the standard state of a material is its state at 1 bar (100 Kilopascals exactly Xenon (ˈzɛnɒn or) is a Chemical element represented by the symbol Xe. Fluorine, fluorum meaning "to flow" is the Chemical element with the symbol F and Atomic number 9 History Noble gas is translated from the German noun de ''Edelgas'' first used in 1898 by Hugo Erdmann to indicate their extremely low level of reactivity It was the first discovered binary compound containing a noble gas[1]. It forms by the reaction of Xe and F2 in the ratio of 1 mol Xe to 2 mol F2. [2][3]The process is exothermic, releasing 251 kJ per mol of Xe[1]. In Thermodynamics, the word exothermic "outside heating" describes a process or reaction that releases Energy usually in the form of Heat, but It occurs as colorless crystals. The structure was determined by NMR spectroscopy and x-ray crystallography in 1963. [4][5]
It sublimes at 115. Sublimation of an element or compound is a transition from the Solid to Gas phase with no intermediate liquid stage 7 °C (240. 26 °F).
Xenon fluorides are all exergonic and stable at normal temperatures. Exergonic means to release energy in the form of work Its etymology stems from the suffix -ergonic, as derived from the Greek root ergon meaning work, They do react readily with water, even pulling water from air, so they must be kept in anhydrous conditions. Water is a common Chemical substance that is essential for the survival of all known forms of Life. As a general term a substance is said to be anhydrous if it contains no Water.
