  2. VSEPR theory - Wikipedia

    en.wikipedia.org/wiki/VSEPR_theory

    VSEPR theory is used to predict the arrangement of electron pairs around central atoms in molecules, especially simple and symmetric molecules. A central atom is defined in this theory as an atom which is bonded to two or more other atoms, while a terminal atom is bonded to only one other atom.

  3. Bismuth chloride - Wikipedia

    en.wikipedia.org/wiki/Bismuth_chloride

    Furthermore, the octahedral structure of this coordination complex does not follow the predictions of VSEPR theory, since the lone pair on bismuth is unexpectedly stereochemically inactive. The dianionic complex [BiCl 5] 2− does however adopt the expected square pyramidal structure. [8]

  4. Iodine heptafluoride - Wikipedia

    en.wikipedia.org/wiki/Iodine_heptafluoride

    Iodine heptafluoride is an interhalogen compound with the chemical formula I F 7. [2] [3] It has an unusual pentagonal bipyramidal structure, with D 5h symmetry, as predicted by VSEPR theory. [4]

  5. Phosphorus pentachloride - Wikipedia

    en.wikipedia.org/wiki/Phosphorus_pentachloride

    The structures for the phosphorus chlorides are invariably consistent with VSEPR theory. The structure of PCl 5 depends on its environment. Gaseous and molten PCl 5 is a neutral molecule with trigonal bipyramidal geometry and (D 3h) symmetry. The hypervalent nature of this species (as well as of PCl −

  6. T-shaped molecular geometry - Wikipedia

    en.wikipedia.org/wiki/T-shaped_molecular_geometry

    According to VSEPR theory, T-shaped geometry results when three ligands and two lone pairs of electrons are bonded to the central atom, written in AXE notation as AX 3 E 2. The T-shaped geometry is related to the trigonal bipyramidal molecular geometry for AX 5 molecules with three equatorial and two axial ligands.

    2. Eat Smaller, More Frequent Meals. Instead of three main meals, try eating smaller, more frequent meals throughout the day. This can help if nausea is making it hard to feel like eating or if ...

  8. Molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Molecular_geometry

    In accordance with the VSEPR (valence-shell electron pair repulsion theory), the bond angles between the electron bonds are arccos(− ⁠ 1 / 3 ⁠) = 109.47°. For example, methane (CH 4) is a tetrahedral molecule. Octahedral: Octa-signifies eight, and -hedral relates to a face of a solid, so "octahedral" means "having eight faces". The bond ...
