In the modern periodic table, elements are arranged in order of increasing atomic number and is based upon the electronic configuration of elements. Depending upon the type of subshell which receives the last electron, the elements in the periodic table have been divided into four blocks, viz., s–, p–, d– and f–. The modern periodic table consisits of 7 periods and 18 groups. Each period beings with the filling of a new energy shell. In accordance with the aufbau principle, the seven periods have 2, 8, 8, 18, 18, 32 and 32 elements respectively. The seventh period still incomplete. To avoid making the period table too long, the two series of f–block elements called lanthanoids and actinoids are placed at the bottom of the main body of the periodic table.
