  2. English compound - Wikipedia

    en.wikipedia.org/wiki/English_compound

    English compound modifiers are constructed in a very similar way to the compound noun. Blackboard Jungle, leftover ingredients, gunmetal sheen, and green monkey disease are only a few examples. A compound modifier is a sequence of modifiers of a noun that function as a single unit.

  3. PG5 (molecule) - Wikipedia

    en.wikipedia.org/wiki/PG5_(molecule)

    PG5 has a molecular mass of about 200 MDa or 200,000,000,000,000,000 g/mol. It has roughly 200 million atoms and a diameter of roughly 10 nm. Its length is up to a few micrometers. [3]

  4. 5-cell - Wikipedia

    en.wikipedia.org/wiki/5-cell

    In geometry, the 5-cell is the convex 4-polytope with Schläfli symbol {3,3,3}. It is a 5-vertex four-dimensional object bounded by five tetrahedral cells. It is also known as a C 5, hypertetrahedron, pentachoron, [1] pentatope, pentahedroid, [2] tetrahedral pyramid, or 4-simplex (Coxeter's polytope), [3] the simplest possible convex 4-polytope, and is analogous to the tetrahedron in three ...

    An ionic compound is a chemical compound composed of ions held together by electrostatic forces termed ionic bonding. The compound is neutral overall, but consists of positively charged ions called cations and negatively charged ions called anions.

  7. Quaternary ammonium cation - Wikipedia

    en.wikipedia.org/wiki/Quaternary_ammonium_cation

    Quaternary ammonium cation. The R groups may be the same or different alkyl or aryl groups. Also, the R groups may be connected. In organic chemistry, quaternary ammonium cations, also known as quats, are positively-charged polyatomic ions of the structure [NR 4] +, where R is an alkyl group, an aryl group [1] or organyl group.

  8. Transition metal oxo complex - Wikipedia

    en.wikipedia.org/wiki/Transition_metal_oxo_complex

    Here it can be seen that d 1-2 electrons fill a nonbonding orbital and electrons d 3-6 fill anti-bonding orbitals, which destabilize the complex. [18] The term "oxo wall" is a theory used to describe the fact that no terminal oxo complexes are known for metal centers with octahedral symmetry and d-electron counts beyond 5. [18] [19]

    After his death in 1821, the French emperor's height was recorded as 5 feet 2 inches in French feet, which in English measurements is 5 feet 7 inches (1.70 m). The nose of the Great Sphinx of Giza was not shot off by Napoleon's troops during the French campaign in Egypt (1798–1801); it has been missing since at least the 10th century.
