chemical symbol

English

Noun

chemical symbol (plural chemical symbols)

1. (chemistry) The 1- to 3-letter international code for a chemical element. It is the same in all languages. Thus, gold always has the chemical symbol "Au", regardless what people call it in their language.
2. (by extension) a similar symbol used to denote a different chemical entity, such as an isotope (e.g. D = deuterium, though "²H" is preferable), a radical (e.g. Ph [or Φ] = phenyl), an unknown (e.g. M = a metal, or X = a halogen), etc.
