  2. Thioformaldehyde - Wikipedia

    en.wikipedia.org/wiki/Thioformaldehyde

    Thioformaldehyde is the organosulfur compound with the formula CH 2 S. It is the simplest thioaldehyde.This compound is not observed in the condensed state (solid or liquid) because it oligomerizes to 1,3,5-trithiane, which is a stable colorless compound with the same empirical formula.

  3. 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 Lewis number can also be expressed in terms of the Prandtl number (Pr) and the Schmidt number (Sc): [5] = It is named after Warren K. Lewis (1882–1975), [6] [7] who was the first head of the Chemical Engineering Department at MIT.

  5. Formal charge - Wikipedia

    en.wikipedia.org/wiki/Formal_charge

    [1] [2] In simple terms, formal charge is the difference between the number of valence electrons of an atom in a neutral free state and the number assigned to that atom in a Lewis structure. When determining the best Lewis structure (or predominant resonance structure) for a molecule, the structure is chosen such that the formal charge on each ...

  9. Electron pair - Wikipedia

    en.wikipedia.org/wiki/Electron_pair

    This also limits the number of electrons in the same orbital to two. The pairing of spins is often energetically favorable, and electron pairs therefore play a large role in chemistry . They can form a chemical bond between two atoms, or they can occur as a lone pair of valence electrons .
