Periodic table

Approximate order in which shells and subshells are arranged by increasing energy according to the Madelung rule

Periodic table trends (arrows direct an increase)

Atomic number plotted against atomic radius[n 4]

The periodic table is a tabular arrangement of the chemical elements, ordered by their atomic number (number of protons), electron configurations, and recurring chemical properties. This ordering shows periodic trends, such as elements with similar behavior in the same column. It also shows four rectangular blocks with some approximately similar chemical properties. In general, within one row (period) the elements are metals on the lefthand side, and non-metals on the righthand side.
