    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 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 ...

    en.wikipedia.org/wiki/Lewis_structure

    Lewis structures – also called Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures (LEDs) – are diagrams that show the bonding between atoms of a molecule, as well as the lone pairs of electrons that may exist in the molecule. [1][2][3] A Lewis structure can be drawn for any covalently bonded ...

    en.wikipedia.org/wiki/Xenon_hexafluoride

    The structure of XeF 6 required several years to establish in contrast to the cases of XeF 2 and XeF 4.In the gas phase the compound is monomeric. VSEPR theory predicts that due to the presence of six fluoride ligands and one lone pair of electrons the structure lacks perfect octahedral symmetry, and indeed electron diffraction combined with high-level calculations indicate that the compound's ...

    The tangent construction shown above is rarely used in interpreting the stress-strain curves of metals. However, it is popular for analysis of the tensile drawing of polymers. [4] [5] (since it allows study of the regime of stable necking). It may be noted that, for polymers, the strain is commonly expressed as a “draw ratio”, rather than a ...
