    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]

  3. Xenon oxytetrafluoride - Wikipedia

    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.

  4. Xenon tetroxide - Wikipedia

    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 ...

    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 ...

  6. Ionic bonding - Wikipedia

    en.wikipedia.org/wiki/Ionic_bonding

    Ionic bonding is a type of chemical bonding that involves the electrostatic attraction between oppositely charged ions, or between two atoms with sharply different electronegativities, [1] and is the primary interaction occurring in ionic compounds. It is one of the main types of bonding, along with covalent bonding and metallic bonding.

    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 ...

    Contributing structures of the carbonate ion. In chemistry, resonance, also called mesomerism, is a way of describing bonding in certain molecules or polyatomic ions by the combination of several contributing structures (or forms, [1] also variously known as resonance structures or canonical structures) into a resonance hybrid (or hybrid structure) in valence bond theory.

  9. Xenon - Wikipedia

    en.wikipedia.org/wiki/Xenon

    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
