This is a list of named alloys grouped alphabetically by the metal with the highest percentage. Within these headings, the alloys are also grouped alphabetically. Within these headings, the alloys are also grouped alphabetically.
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 ...
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). Elements which have only temporary systematic names are given temporary three-letter symbols (e.g. Uue for ununennium, the undiscovered ...
Many classical compositions belong to a numbered series of works of a similar type by the same composer. For example, Beethoven wrote 9 symphonies, 10 violin sonatas, 32 piano sonatas, 5 piano concertos, 16 string quartets, 7 piano trios and other works, all of which are numbered sequentially within their genres and generally referred to by their sequence numbers, keys and opus numbers.
For isotopes of undiscovered elements, either systematic names (e.g. 296 Uue) or atomic numbers (e.g. 296 119) are acceptable for the symbols, but only the systematic names can be used for the full names (e.g. ununennium-296, not element 119-296 which nobody uses).
41 of the 118 known elements have names associated with, or specifically named for, places around the world or among astronomical objects. 32 of these have names tied to the places on Earth, and the other nine are named after to Solar System objects: helium for the Sun; tellurium for the Earth; selenium for the Moon; mercury (indirectly), uranium, neptunium and plutonium after their respective ...
Provincial titles are those with authority over a constituent state, such as a United States governor. Regional titles are those with authority over multiple constituent states, such as a federal judge. Courtly titles have no sovereign power of their own but are granted high prestige by, and are possibly able to exert influence over, a head of ...
initialism = an abbreviation pronounced wholly or partly using the names of its constituent letters, e.g., CD = compact disc, pronounced cee dee; pseudo-blend = an abbreviation whose extra or omitted letters mean that it cannot stand as a true acronym, initialism, or portmanteau (a word formed by combining two or more words).
