The noble gases (Group 18) are located in the far right of the periodic table and were previously referred to every bit the "inert gases" due to the fact that their filled valence shells (octets) brand them extremely nonreactive.

The Chemical Properties

Noble gases are odorless, colorless, nonflammable, and monotonic gases that have depression chemical reactivity.

Atomic Number	Chemical element	Number of Electrons/Shell
two	Helium	2
10	Neon	two,8
eighteen	Argon	2,8,8
36	Krypton	2,8,18,8
54	Xenon	2,eight,eighteen,18,8
86	Radon	2,8,18,32,18,8

The full valence electron shells of these atoms make noble gases extremely stable and unlikely to class chemical bonds considering they take picayune tendency to gain or lose electrons. Although noble gases do not ordinarily react with other elements to form compounds, in that location are some exceptions. Xe may form compounds with fluoride and oxide.

Example 1: Xenon Fluorides

Xenon Difluoride (\(XeF_2\))

Dense white crystallized solid
Powerful fluorinating agent
Covalent inorganic fluorides
Stable xenon chemical compound
Decomposes on contact with calorie-free or water vapor
Linear geometry
Wet sensitive
Low vapor force per unit area

Xenon Tetrafluoride (\(XeF_4\))

Figure: On Oct. 2, 1963, Argonne announced the creation of xenon tetrafluoride, the first uncomplicated compound of xenon, a element of group 0 widely thought to be chemically inert.

Colorless Crystals
Foursquare planar geometry
Discovered in 1963

Xenon Hexafluoride (\(XeF_6\))

Figure used with permission from Wikipedia.

Strongest fluorinating agent
Colorless solid
Highest coordination of the three binary fluorides of xenon (\(XeF_2\) and \(XeF_4\))
Germination is exergonic, and the compound is stable at normal temperatures
Readily sublimes into intense xanthous vapors
Structure lacks perfect octahedral symmetry

Example 2: Xenon Oxide

Xenon Tetroxide (XeO₄)

Yellow crystalline solid
Relatively stable
Oxygen is the only element that can bring xenon upward to its highest oxidation state of +8

Two other curt-lived xenon compounds with an oxidation state of +8, XeO_threeF₂ and XeO₂F_iv, are produced in the reaction of xenon tetroxide with xenon hexafluoride.

Example 3: Radon Compounds

Radon difluoride (RnF₂) is one of the few reported compounds of radon. Radon reacts readily with fluorine to form a solid compound, but this decomposes on attempted vaporization and its exact limerick is uncertain. The usefulness of radon compounds is limited because of the element of group 0'southward radioactive decay. The longest-lived isotope, ²²²Ra, has a half-life of merely 3.82 days.
