Interactive periodic table showing names, electrons, and oxidation states. Visualize trends, 3D orbitals, isotopes, and mix compounds. Fully descriptive writeups.

The periodic table, also known as the periodic table of the elements, is an ordered arrangement of the chemical elements into rows ("periods") and columns ("groups"). It is an icon of chemistry and is widely used in physics and other sciences.

View the latest release of the Periodic Table (dated 8 Jan 2016) includes the recently added elements 113, 115, 117, and 118 with their temporary names and symbols

Interactive periodic table with up-to-date element property data collected from authoritative sources. Look up chemical element names, symbols, atomic masses and other properties, visualize trends, or even test your elements knowledge by playing a periodic table game!

These periodic tables use accurate data for name, atomic number, element symbol, atomic weight, and electron configuration, obtained from the International Union of Pure and Applied Chemistry or IUPAC. What we’ve done is list the tables, along with links, so you can get detailed info about each one.

2025年2月9日 · Periodic table, in chemistry, the organized array of all the chemical elements in order of increasing atomic number. When the elements are thus arranged, there is a recurring pattern called the ‘periodic law’ in their properties, in which elements in the same column (group) have similar properties.

2009年7月30日 · The periodic table contains NIST’s latest critically evaluated data for atomic properties of the elements. The PDF is suitable for high-resolution color printing for desk or wall-chart display. Access the Table:
