The noble gases (Group 18) are situated in the much ideal of the routine 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 steustatiushistory.orgical Properties

Noble gases are odorless, colorless, nonflammable, and monotonic gases that have actually low steustatiushistory.orgical 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 steady and unmost likely to form steustatiushistory.orgical bonds because they have actually little tendency to obtain or lose electrons. Although noble gases perform not commonly react through various other facets to form compounds, tright here are some exceptions. Xe may create compounds via fluoride and oxide.


Example 1: Xenon Fluorides

Xenon Difluoride ((XeF_​2))

*

Dense white crystallized solid Powerful fluorinating agent Covalent not natural fluorides Stable xenon compound Decomposes on call with light or water vapor Linear geomeattempt Moisture sensitive Low vapor pressure

Xenon Tetrafluoride ((XeF_4))

Figure: On Oct. 2, 1963, Argonne announced the development of xenon tetrafluoride, the initially basic compound of xenon, a noble gas commonly thought to be steustatiushistory.orgically inert. Colorless Crystals Square planar geomeattempt Disextended in 1963

Xenon Hexafluoride ((XeF_6))

*
Figure offered through permission from Wikipedia. Strongest fluorinating agent Colormuch less solid Highest coordicountry of the 3 binary fluorides of xenon ((XeF_2) and (XeF_4)) Formation is exergonic, and also the compound is stable at normal temperatures Readily sublimes right into intense yellow vapors Structure lacks perfect octahedral symmetry

Example 2: Xenon Oxide

Xenon Tetroxide (XeO​4)
