List of Chemical Elements and their Symbols. Carbon is one of the few elements known since antiquity. [209], indicates the mass number of the longest-lived isotope of the element. In many cases, these compounds have a fixed composition and their own structure and properties. Each element is given its own chemical symbol, like H for hydrogen or O for oxygen. Chemical symbols of elements come from their English or Latin names. Name restricted at one time to 227 Ac, an isotope of actinium. C is the chemical symbol for which element with the atomic number 6? Such new structures are not compounds. A 3-letter temporary symbol may be assigned to a newly synthesized (or not yet synthesized) element. These elements are called semimetals (or metalloids). At room temperature and pressure, most elements are solids, only 11 are gases and 2 are liquids. Earlier symbols for chemical elements stem from classical Latin and Greek vocabulary. c. Each element is represented by a unique chemical symbol, a one- or two-letter abbreviation for the element that appears directly below its atomic number on the periodic table. Carbon is the 15th most abundant element in the Earthâs crust, and the fourth most abundant element in the universe by mass after hydrogen, helium, and oxygen. In some cases, the first letter together with some other letter from their name was used, particularly when their first two letters had already been allocated to another element.
