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 ...
118 chemical elements have been identified and named officially by IUPAC.A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z).
The main structure of chemical names according to IUPAC nomenclature.

For internet dictionaries with limited or no formal editorial process, definitions —in this case, definitions of chemical names and terms— can change rapidly without concern for the ...
The formal list is used. The name of the most electronegative element is modified to end in -ide and the more electropositive elements name is left unchanged. Taking the binary compound of sodium and chlorine: chlorine is found first in the list so therefore comes last in the name. Other examples are PCl 5 phosphorus pentachloride
A number of other elements are named after classical words for various places. Ruthenium is from the Latin name for the region including Belarus, Ukraine, and Russia. [29] Lutetium is named after Lutetia, the Latin name for Paris. Copper's name comes from an Old English word derived from the Latin name for the island of Cyprus. [30]
The alkyl (R') group is named first. The R−C(=O)O part is then named as a separate word based on the carboxylic acid name, with the ending changed from "-oic acid" to "-oate" or "-carboxylate" For example, CH 3 CH 2 CH 2 CH 2 COOCH 3 is methyl pentanoate, and (CH 3) 2 CHCH 2 CH 2 COOCH 2 CH 3 is ethyl 4-methylpentanoate.
