  7. Salt (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Salt_(chemistry)

    Humans have processed common salt (sodium chloride) for over 8000 years, using it first as a food seasoning and preservative, and now also in manufacturing, agriculture, water conditioning, for de-icing roads, and many other uses. [83] Many salts are so widely used in society that they go by common names unrelated to their chemical identity.

  8. Coordinate covalent bond - Wikipedia

    en.wikipedia.org/wiki/Coordinate_covalent_bond

    In coordination chemistry, a coordinate covalent bond, [1] also known as a dative bond, [2] dipolar bond, [1] or coordinate bond [3] is a kind of two-center, two-electron covalent bond in which the two electrons derive from the same atom.

  9. Covalent radius - Wikipedia

    en.wikipedia.org/wiki/Covalent_radius

    The covalent radius, r cov, is a measure of the size of an atom that forms part of one covalent bond.It is usually measured either in picometres (pm) or angstroms (Å), with 1 Å = 100 pm.
