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). [ 1 ] The definitive visualisation of all 118 elements is the periodic table of the elements , whose history along the principles of the periodic law was one of the founding ...
Elements with atomic number Z ≥ 119 are theoretical elements, they have not been discovered (synthesized). Regarding public-page creation and content (reader-visible pages, such as artricle, category, template): Element page: Articles pages, by systematic name, exist for E119 up to E184: Ununennium (Element 119).
The first letter is always capitalized. While the symbol is often a contraction of the element's name, it may sometimes not match the element's English name; for example, "Pb" for lead (from Latin plumbum) or "W" for tungsten (from German Wolfram).

[13] [14] At last, a committee of the International Union of Pure and Applied Chemistry (IUPAC) resolved the dispute and adopted one name for each element. They also adopted a temporary systematic ...
