  2. Nitrogen trichloride - Wikipedia

    en.wikipedia.org/wiki/Nitrogen_trichloride

    Nitrogen trichloride, also known as trichloramine, is the chemical compound with the formula NCl 3.This yellow, oily, and explosive liquid is most commonly encountered as a product of chemical reactions between ammonia-derivatives and chlorine (for example, in swimming pools).

  3. Magnesium oxide - Wikipedia

    en.wikipedia.org/wiki/Magnesium_oxide

    Magnesium oxide (Mg O), or magnesia, is a white hygroscopic solid mineral that occurs naturally as periclase and is a source of magnesium (see also oxide). It has an empirical formula of MgO and consists of a lattice of Mg 2+ ions and O 2− ions held together by ionic bonding .

  4. Lewis structure - Wikipedia

    en.wikipedia.org/wiki/Lewis_structure

    [1] [2] [3] Introduced by Gilbert N. Lewis in his 1916 article The Atom and the Molecule, a Lewis structure can be drawn for any covalently bonded molecule, as well as coordination compounds. [4] Lewis structures extend the concept of the electron dot diagram by adding lines between atoms to represent shared pairs in a chemical bond.

    The dot-and-cross diagram of the LDQ structure of the ground state of acetylene is shown on the left and that of the first excited state of acetylene is shown on the right. The nuclei are as indicated and the electrons are denoted by either dots or crosses, depending on their relative spins.

  7. Frost diagram - Wikipedia

    en.wikipedia.org/wiki/Frost_diagram

    Note: This Frost diagram for nitrogen is also incomplete as it lacks azide (N − 3, or hydrazoic acid, HN 3), presented here above in the former Frost diagram for nitrogen. The pH dependence is given by the factor −0.059 m / n per pH unit, where m relates to the number of protons in the equation, and n the number of electrons exchanged.

  8. Molecular orbital diagram - Wikipedia

    en.wikipedia.org/wiki/Molecular_orbital_diagram

    Molecular orbital diagram of NO. Nitric oxide is a heteronuclear molecule that exhibits mixing. The construction of its MO diagram is the same as for the homonuclear molecules. It has a bond order of 2.5 and is a paramagnetic molecule. The energy differences of the 2s orbitals are different enough that each produces its own non-bonding σ orbitals.

  9. Magnesium nitride - Wikipedia

    en.wikipedia.org/wiki/Magnesium_nitride

    Magnesium nitride reacts with water to produce magnesium hydroxide and ammonia gas, as do many metal nitrides.. Mg 3 N 2 (s) + 6 H 2 O(l) → 3 Mg(OH) 2 (aq) + 2 NH 3 (g). In fact, when magnesium is burned in air, some magnesium nitride is formed in addition to the principal product, magnesium oxide.
