Note that "group" has a chemical meaning and "column" has the tabular meaning. Alternatively, they may be named by their first element, e.g. "boron group" for group 13. [2] (But per below, avoid iron group for group 8 as ambiguous.) In the 1–18 scheme, f-block groups are unnumbered.
Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
The main structure of chemical names according to IUPAC nomenclature. IUPAC nomenclature is a set of recommendations for naming chemical compounds and for describing chemistry and biochemistry in general. The International Union of Pure and Applied Chemistry (IUPAC) is the international authority on chemical nomenclature and terminology.
The -ine suffix is used only for the halogens, with chlorine being named first, and the others being named to match. The suffix -gen is used for three other nonmetals forming diatomic molecules (hydrogen, nitrogen, and oxygen). Suffixes were used more inconsistently before 1784, with tungsten (discovered 1783) the last element discovered whose ...
A name suffix in the Western English-language naming tradition, follows a person's surname (last name) and provides additional information about the person. Post-nominal letters indicate that the individual holds a position, educational degree, accreditation, office, or honor (e.g. " PhD ", " CCNA ", " OBE ").
The shorter of the two chains becomes the first part of the name with the -ane suffix changed to -oxy, and the longer alkane chain becomes the suffix of the name of the ether. Thus, CH 3 OCH 3 is methoxymethane, and CH 3 OCH 2 CH 3 is methoxyethane (not ethoxymethane). If the oxygen is not attached to the end of the main alkane chain, then the ...

The main purpose of chemical nomenclature is to disambiguate the spoken or written names of chemical compounds: each name should refer to one compound. Secondarily, each compound should have only one name, although in some cases some alternative names are accepted. Preferably, the name should also represent the structure or chemistry of a compound.
