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) The modern periodic table is based closely on the ideas he used: the elements are shown by the symbol for their atom the elements are arranged in mass order (order of increasing atomic number).

For more detailed information about the origins of element names, see List of chemical element name etymologies. Chemistry Reference Table BRF File (UEB) Documents. 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. 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 the same number of protons in its atomic nucleus (i.e., the same atomic number, or Z). B1: Workfunction Values (Reference Table) - Chemistry LibreTexts B1: Workfunction Values (Reference Table) Last updated Bulk Properties B2: Heats of Vaporization (Reference Table) Work function of elements, in units of electron volt (eV). This is a list of the 118 chemical elements that have been identified as of 2023. Periodic Table: Atomic Properties of the Elements Contains NIST critically-evaluated data on atomic properties of the elements. Examples: The atomic number of the first element, hydrogen, is 1. Physical Reference Data Elemental Data Index Provides access to the holdings of NIST Physical Measurement Laboratory online data organized by element. List of the 118 identified chemical elements Below is a periodic table that you can print out and use as a reference while taking chemistry courses, going through quizzes, or taking an exam through . The lowest atomic number is 1 ( hydrogen ), while the highest atomic number is 118.
