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.
Two other predicted elements were later discovered, lending further credit to Mendeleev's table. Modern day periodic tables are expanded beyond Mendeleev's initial 63 elements. Most of the current periodic tables include 108 or 109 elements. It is also important to notice how the modern periodic table is arranged. Although we have retained the format of rows and columns, which reflects a natural order, the rows of today's tables show elements in the order of Mendeleev's columns.
