  2. Nitrogen monofluoride - Wikipedia

    en.wikipedia.org/wiki/Nitrogen_monofluoride

    Nitrogen monofluoride (fluoroimidogen) is a metastable species that has been observed in laser studies. It is isoelectronic with O 2. Like boron monofluoride, it is an instance of the rare multiply-bonded fluorine atom. [1] [2] It is unstable with respect to its formal dimer, dinitrogen difluoride, as well as to its elements, nitrogen and fluorine.

  3. Molecular model - Wikipedia

    en.wikipedia.org/wiki/Molecular_model

    The construction of physical models is often a creative act, and many bespoke examples have been carefully created in the workshops of science departments. There is a very wide range of approaches to physical modeling, including ball-and-stick models available for purchase commercially, to molecular models created using 3D printers. The main ...

  4. Nitrogen pentahydride - Wikipedia

    en.wikipedia.org/wiki/Nitrogen_pentahydride

    Nitrogen pentahydride, also known as ammonium hydride is a hypothetical compound with the chemical formula NH 5. There are two theoretical structures of nitrogen pentahydride. One structure is trigonal bipyramidal molecular geometry type NH 5 molecule. Its nitrogen atom and hydrogen atoms are covalently bounded, and its symmetry group is D 3h. [1]

  5. van der Waals surface - Wikipedia

    en.wikipedia.org/wiki/Van_der_Waals_surface

    Methane, CH 4, space-filling, van der Waals-based representation, carbon (C ) in black, hydrogen (H) in white.In chemistry, a space-filling model is a type of three-dimensional (3D) molecular model where the atoms are represented by spheres whose radii are, either as van der Waals radii or otherwise, proportional to the radii of the atoms.

    The individual atoms of the polypeptide have been hidden. All of the non-hydrogen atoms in the two ligands are shown near the top of the diagram. Ribbon diagrams are schematic representations of protein structure and are one of the most common methods of protein depiction used today. The ribbon shows the overall path and organization of the ...

  7. Space-filling model - Wikipedia

    en.wikipedia.org/wiki/Space-filling_model

    A space-filling model of n-octane, the straight chain (normal) hydrocarbon composed of 8 carbons and 18 hydrogens, formulae: CH 3 CH 2 (CH 2) 4 CH 2 CH 3 or C 8 H 18.Note, the representative shown is of a single conformational "pose" of a population of molecules, which, because of low Gibbs energy barriers to rotation about its carbon-carbon bonds (giving the carbon "chain" great flexibility ...

  8. Molecular orbital diagram - Wikipedia

    en.wikipedia.org/wiki/Molecular_orbital_diagram

    For a diatomic molecule, an MO diagram effectively shows the energetics of the bond between the two atoms, whose AO unbonded energies are shown on the sides. For simple polyatomic molecules with a "central atom" such as methane (CH 4) or carbon dioxide (CO 2), a MO diagram may show one of the identical bonds to the central atom. For other ...

  9. Nitronium ion - Wikipedia

    en.wikipedia.org/wiki/Nitronium_ion

    The nitronium ion, [N O 2] +, is a cation.It is an onium ion because its nitrogen atom has +1 charge, similar to ammonium ion [NH 4] +.It is created by the removal of an electron from the paramagnetic nitrogen dioxide molecule NO 2, or the protonation of nitric acid HNO 3 (with removal of H 2 O).
