Trivial name
In chemistry, a trivial name is a non-systematic name for a chemical substance. That is, the name is not recognized according to the rules of any formal system of chemical nomenclature such as IUPAC inorganic or IUPAC organic nomenclature. A trivial name is not a formal name and is usually a common name.
Generally, trivial names are not useful in describing the essential properties of the thing named, such as the molecular structure of a chemical compound. And, in some cases, trivial names can be ambiguous or carry different meanings in different industries or different geographic regions (for example, a trivial name such as white metal can mean various things). A limited number of trivial chemical names are retained names, an accepted part of the nomenclature.
Trivial names often arise in the common language; they may come from historical usages in, for example, alchemy. Many trivial names pre-date the institution of formal naming conventions. Names can be based on a property of the chemical, including appearance (color, taste or smell), consistency, and crystal structure; a place where it was found or where the discoverer comes from; the name of a scientist; a mythological figure; an astronomical body; the shape of the molecule; and even fictional figures. All elements that have been isolated have trivial names.
In scientific documents, international treaties, patents and legal definitions, names for chemicals are needed that identify them unambiguously. This need is satisfied by systematic names. One such system, established by the International Union of Pure and Applied Chemistry (IUPAC), was established in 1950. Other systems have been developed by the American Chemical Society, the International Organization for Standardization, and the World Health Organization. However, chemists still use many names that are not systematic because they are traditional or because they are more convenient than the systematic names. These are called trivial names. The word "trivial", often used in a pejorative sense, was intended to mean "commonplace".
In addition to trivial names, chemists have constructed semi-trivial names by appending a standard symbol to a trivial stem. Some trivial and semi-trivial names are so widely used that they have been officially adopted by IUPAC; these are known as retained names.
The common names used for pesticides did not become commonplace through repeated informal usage, The names are granted by ISO committee (TC81), who approve the common name according to ISO1750.
Traditional names of elements are trivial, some originating in alchemy. IUPAC has accepted these names, but has also defined systematic names of elements that have not yet been prepared. It has adopted a procedure by which the scientists who are credited with preparing an element can propose a new name. Once the IUPAC has accepted such a (trivial) name, it replaces the systematic name.
Nine elements were known by the Middle Ages: gold, silver, tin, mercury, copper, lead, iron, sulfur, and carbon. Mercury was named after the planet, but its symbol was derived from the Latin hydrargyrum, which itself comes from the Greek υδράργυρος, meaning liquid silver; mercury is also known as quicksilver in English. The symbols for the other eight are derived from their Latin names.
