The noble gases (Group 18) are situated in the much ideal of the routine table and were formerly described as the "inert gases" due to the fact that their filled valence shells (octets) make them very nonreenergetic.

The slrfc.orgical Properties

Noble gases are odorless, colorless, nonflammable, and monotonic gases that have low slrfc.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 full valence electron shells of these atoms make noble gases very stable and also unlikely to develop slrfc.orgical bonds bereason they have actually little tendency to gain or shed electrons. Although noble gases perform not generally react through other elements to create compounds, tbelow are some exceptions. Xe might 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 geometry Moisture sensitive Low vapor pressure

Xenon Tetrafluoride ((XeF_4))

Figure: On Oct. 2, 1963, Argonne announced the production of xenon tetrafluoride, the initially easy compound of xenon, a noble gas widely thmust be slrfc.orgically inert. Colormuch less Crystals Square planar geometry Disspanned in 1963

Xenon Hexafluoride ((XeF_6))

*
Figure offered through permission from Wikipedia. Strongest fluorinating agent Colormuch less solid Highest coordination of the 3 binary fluorides of xenon ((XeF_2) and also (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)
