Periodic Table Of Elements
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. Scientists use the periodic table to quickly refer to information
about an element, like atomic mass and chemical symbol. The periodic table’s arrangement
also allows scientists to discern trends in element properties, including electronegativity,
ionization energy, and atomic radius.
