    en.wikipedia.org/wiki/Xenon_tetrafluoride

    Xenon tetrafluoride is a colorless crystalline solid that sublimes at 117 °C. Its structure was determined by both NMR spectroscopy and X-ray crystallography in 1963. [6][7] The structure is square planar, as has been confirmed by neutron diffraction studies. [8]

    en.wikipedia.org/wiki/Xenon_tetroxide

    Xenon tetroxide is a chemical compound of xenon and oxygen with molecular formula XeO 4, remarkable for being a relatively stable compound of a noble gas. It is a yellow crystalline solid that is stable below −35.9 ° C; above that temperature it is very prone to exploding and decomposing into elemental xenon and oxygen (O 2). [ 4 ][ 5 ] All ...

    en.wikipedia.org/wiki/Xenon_compounds

    Xenon compounds are compounds containing the element xenon (Xe). After Neil Bartlett's discovery in 1962 that xenon can form chemical compounds, a large number of xenon compounds have been discovered and described. Almost all known xenon compounds contain the electronegative atoms fluorine or oxygen. The chemistry of xenon in each oxidation ...

    The σ from the 2p is more non-bonding due to mixing, and same with the 2s σ. This also causes a large jump in energy in the 2p σ* orbital. The bond order of diatomic nitrogen is three, and it is a diamagnetic molecule. [12] The bond order for dinitrogen (1σ g 2 1σ u 2 2σ g 2 2σ u 2 1π u 4 3σ g 2) is three because two electrons are now ...

    4, at −100 °C. [115] [122] An unusual ion containing xenon is the tetraxenonogold(II) cation, AuXe 2+ 4, which contains Xe–Au bonds. [123] This ion occurs in the compound AuXe 4 (Sb 2 F 11) 2, and is remarkable in having direct chemical bonds between two notoriously unreactive atoms, xenon and gold, with xenon acting as a transition metal ...

    The bond angle for water is 104.5°. Valence shell electron pair repulsion (VSEPR) theory (/ ˈvɛspər, vəˈsɛpər / VESP-ər, [ 1 ]: 410və-SEP-ər[ 2 ]) is a model used in chemistry to predict the geometry of individual molecules from the number of electron pairs surrounding their central atoms. [ 3 ] It is also named the Gillespie-Nyholm ...

    en.wikipedia.org/wiki/Xenon_oxytetrafluoride

    Infobox references. Xenon oxytetrafluoride (Xe O F. 4) is an inorganic chemical compound. It is an unstable colorless liquid [2][3] with a melting point of −46.2 °C (−51.2 °F; 227.0 K) [4] that can be synthesized by partial hydrolysis of XeF. 6, or the reaction of XeF. 6 with silica [3] or NaNO. 3: [5] NaNO. 3 + XeF.

    These compounds have found use in the study of the structure and reactivity of fullerenes by means of the nuclear magnetic resonance of the noble gas atom. [65] Bonding in XeF 2 according to the 3-center-4-electron bond model. Noble gas compounds such as xenon difluoride (XeF 2) are considered to be hypervalent because they violate the octet rule.
