The Journal of Physical Chemistry Letters 2014, 5 (24) , 4336-4342. It lacks perfect octahedral symmetry, as predicted by VSEPR theory due to the presence of six fluoride ligands and one lone pair of electrons. It is a colorless solid, at room temperature. XeF6 serves as a Lewis acid, binding one and two fluoride anions: The two other binary fluorides do not form such stable adducts with fluoride. This question needs details or clarity. So far, more than 100 compounds of xenon have been synthesized. The salt Rb2XeF8 is among the most robust xenon compounds, decomposing only above 400 °C.[3]. In most of the compounds, the oxidation state of xenon is similar to its neighbouring element Iodine in the immediately lower oxidation state. It is also used as neuro and cardioprotective. It lacks perfect octahedral symmetry, as predicted by VSEPR theory due to the presence of six fluoride ligands and one lone pair of electrons. In the gas phase it adopts a slightly distorted octahedral geometry. It can also be found in some of the extracted minerals from the earth. Fluorine. Read About the Structure of Xenon Hexafluoride in the Journal of Chemical Physics. The reason for low territorial xenon on Earth can be explained by the covalent bonding of xenon and oxygen within Quartz, which can trap xenon from escaping into the atmosphere. Fluorescent lamps and "neon" lights are examples of this process. Phase at room temperature: Gas 6. Xenon currently finds its uses as the free element. It is a colourless crystalline solid and can sublimate. Due to the relatively small width of metallic Xenon, it absorbs red light and emits blue light, which is unusual in metals. With HF, it gives an ionic compound [{ XeF }_{ 5 }]^{ + }+[{ HF }_{ 2 }]^{ - }. Xenon is generally used as an anaesthetic, though it is not a cheaper alternative. It is prepared by treating Barium Perxenate ({ Ba }_{ 2 }{ XeO }_{ 6 }) with anhydrous sulphuric acid. It is a very powerful oxidizing agent, and liberates oxygen from water slowly, accelerated by exposure to sunlight. Keeping xenon … It is therefore preferred as a propellant for ion propulsion of space-crafts. Xenon is a rare, colorless, odorless heavy gas. The concept couldn’t have been simpler: take xenon, in one flask, and vapour of platinum hexafluoride in another, and let them mix together.
