The Chemistry Division's Periodic Table describes the history, properties, resources, uses, isotopes, forms, costs, and other information for each element.

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). ![]() It is an organizing icon of chemistry and is widely used in physics and other sciences. This is a list of the 118 chemical elements that have been identified as of 2023. The periodic table, also known as the periodic table of the elements, arranges the chemical elements into rows ('periods') and columns ('groups').
