The periodic table of chemical elements, often called the periodic table, organizes all discovered chemical elements in rows (called periods) and columns (called groups) according to increasing atomic number.
Aug 7, 2025 · 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.
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 …
