THE ELEMENTS

The following is a table of chemical elements ordered by atomic number and color coded according to type of element. Given is each element's name, element symbol, group and period, atomic weight (or most stable isotope), and certain chemical properties. This list of the elements and their properties is intended as a quick reference.
