This online quiz is intended to give you extra practice in naming chemical compounds, including ionic compounds made from simple or polyatomic ions, binary molecular compounds, or common acids. Magnesia, a district of Eastern Thessaly in GreeceĪlumina, from Latin alumen (gen. Naming Compounds & Calculating Molar Masses Quiz. Symbol Na is derived from Neo-Latin natrium, coined from German Natron, ' natron'.Greek elements hydro- and -gen, ' water-forming'īeryl, a mineral (ultimately from the name of Belur in southern India) īorax, a mineral (from Arabic bawraq, Middle Persian * bōrag)Ĭoined by Humphry Davy who first isolated it, from English soda (specifically caustic soda), via Italian from Arabic ṣudāʕ 'headache' ![]() For more detailed information about the origins of element names, see List of chemical element name etymologies. 2: Names of Some Polyatomic Ionic Compounds. by naming first the cation and then the anion. Like the periodic table, the list below organizes the elements by the number of protons in their atoms it can also be organized by other properties, such as atomic weight, density, and electronegativity. Compounds containing polyatomic ions are named similarly to those containing only monatomic ions, i.e. It is a tabular arrangement of the elements by their chemical properties that usually uses abbreviated chemical symbols in place of full element names, but the linear list format presented here is also useful. 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 developments of modern chemistry. 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). ![]() As of February 2024, 118 chemical elements have been identified and named officially by IUPAC. ![]()
