  2. Lewis structure - Wikipedia

    en.wikipedia.org/wiki/Lewis_structure

    Lewis structures – also called Lewis dot formulas, ... Nitrogen is the least electronegative atom of the two, so it is the central atom by multiple criteria.

  3. Structural formula - Wikipedia

    en.wikipedia.org/wiki/Structural_formula

    Lewis structures (or "Lewis dot structures") are flat graphical formulas that show atom connectivity and lone pair or unpaired electrons, but not three-dimensional structure. This notation is mostly used for small molecules. Each line represents the two electrons of a single bond. Two or three parallel lines between pairs of atoms represent ...

  4. Tetrasulfur tetranitride - Wikipedia

    en.wikipedia.org/wiki/Tetrasulfur_tetranitride

    S 4 N 4 is a Lewis base at nitrogen. It binds to strong Lewis acids, such as SbCl 5 and SO 3, or H[BF 4]: S 4 N 4 + SbCl 5 → S 4 N 4 ·SbCl 5 S 4 N 4 + SO 3 → S 4 N 4 ·SO 3 S 4 N 4 + H[BF 4] → [S 4 N 4 H] + [BF 4] −. The cage is distorted in these adducts. [1] S 4 N 4 reacts with metal complexes, but the bonding situation may be quite ...

  5. Electron counting - Wikipedia

    en.wikipedia.org/wiki/Electron_counting

    It is used for classifying compounds and for explaining or predicting their electronic structure and bonding. [1] Many rules in chemistry rely on electron-counting: Octet rule is used with Lewis structures for main group elements , especially the lighter ones such as carbon , nitrogen , and oxygen ,

  6. Nitrate radical - Wikipedia

    en.wikipedia.org/wiki/Nitrate_radical

    Nitrogen trioxide or nitrate radical is an oxide of nitrogen with formula NO 3 , consisting of three oxygen atoms covalently bound to a nitrogen atom. This highly unstable blue compound has not been isolated in pure form, but can be generated and observed as a short-lived component of gas, liquid, or solid systems.

  7. Nitrogen - Wikipedia

    en.wikipedia.org/wiki/Nitrogen

    Nitrogen is a chemical element; it has symbol N and atomic number 7. Nitrogen is a nonmetal and the lightest member of group 15 of the periodic table, often called the pnictogens. It is a common element in the universe, estimated at seventh in total abundance in the Milky Way and the Solar System.

  8. Phosphorus mononitride - Wikipedia

    en.wikipedia.org/wiki/Phosphorus_mononitride

    Phosphorus mononitride is an inorganic compound with the chemical formula P N.Containing only phosphorus and nitrogen, this material is classified as a binary nitride. From the Lewis structure perspective, it can be represented with a P-N triple bond with a lone pair on each atom.

    en.wikipedia.org/wiki/Nitrogen_compounds

    Many other binary nitrogen hydrides are known, but the most important are hydrazine (N 2 H 4) and hydrogen azide (HN 3). Although it is not a nitrogen hydride, hydroxylamine (NH 2 OH) is similar in properties and structure to ammonia and hydrazine as well. Hydrazine is a fuming, colourless liquid that smells similarly to ammonia.
