The Periodic Table Listing is an arrangement of the chemical elements, organized on the basis of their atomic numbers, electron configurations, and recurring chemical properties. It consists of elements, which are the simplest form of matter that cannot be broken down into simpler substances by chemical means. The elements are listed in order of increasing atomic number, with the symbol of each ELEMENT given alongside its name. The table also provides information about the ELEMENT's atomic mass, electronegativity, and other properties.
