<h3>How are elements named?</h3>

Elements have been given names based on a variety of factors, including their characteristics, the compound or ore from which they were extracted, the method by which they were found or acquired, mythical characters, locations, and well-known individuals. Some components have names that are descriptive and are based on one of their attributes.

The International Union of Pure and Applied Chemistry chooses the official element names and symbols (IUPAC). However, different nations frequently use similar names and symbols for elements. Official names and symbols for elements are not given until after their discovery has been confirmed. The discoverer may then suggest a name and a symbol.

There are name standards for several element groupings. Names of halogens end in -ine. All noble gas names, save helium, end in -on. The names of most other elements finish with -ium.
