The noble gases (Group 18) are located in the much appropriate of the periodic table and also were formerly described as the "inert gases" as a result of the reality that their filled valence shells (octets) make them incredibly nonreactive.

The lutz-heilmann.infoical Properties

Noble gases are odorless, colormuch less, nonflammable, and monotonic gases that have actually low lutz-heilmann.infoical reactivity.

Atomic Number Element Number of Electrons/Shell
2 Helium 2
10 Neon 2,8
18 Argon 2,8,8
36 Krypton 2,8,18,8
54 Xenon 2,8,18,18,8
86 Radon 2,8,18,32,18,8

The complete valence electron shells of these atoms make noble gases very stable and unmost likely to form lutz-heilmann.infoical bonds because they have actually bit tendency to get or lose electrons. Although noble gases execute not typically react via other elements to form compounds, tright here are some exceptions. Xe may develop compounds through fluoride and oxide.

Example 1: Xenon Fluorides

Xenon Difluoride ((XeF_​2))


Dense white crystallized solid Powerful fluorinating agent Covalent inorganic fluorides Stable xenon compound Decomposes on contact via light or water vapor Liclose to geomeattempt Moisture sensitive Low vapor pressure

Xenon Tetrafluoride ((XeF_4))

Figure: On Oct. 2, 1963, Argonne announced the development of xenon tetrafluoride, the first simple compound of xenon, a noble gas extensively thneed to be lutz-heilmann.infoically inert. Colormuch less Crystals Square planar geometry Disspanned in 1963

Xenon Hexafluoride ((XeF_6))

Figure provided via permission from Wikipedia. Strongest fluorinating agent Colormuch less solid Highest coordination of the three binary fluorides of xenon ((XeF_2) and (XeF_4)) Formation is exergonic, and also the compound is steady at normal temperatures Readily sublimes into intense yellow vapors Structure lacks perfect octahedral symmetry

Example 2: Xenon Oxide

Xenon Tetroxide (XeO​4)
