At the present time, the periodic table of elements has a total of 118 elements which have been discovered to date. The Madelung energy ordering rule describes the order in which orbitals are arranged by increasing energy according to the Madelung rule.
In general, within one row (period) the elements are metals on the left, and non-metals on the right. The rows of the table are called periods; the columns are called groups. Six groups (columns) have names as well as numbers: for example, group 17 elements are the halogens; and group 18, the noble gases. The periodic table can be used to derive relationships between the properties of the elements, and predict the properties of new elements yet to be discovered or synthesized.
