The periodic table , also known as the periodic table of elements , is a tabular display of the chemical elements , which are arranged by atomic number , electron configuration , and recurring chemical properties. The structure of the table shows periodic trends. The seven rows of the table, called periods , generally have metals on the left and nonmetals on the right. The columns, called groups , contain elements with similar chemical behaviours. Six groups have accepted names as well as assigned numbers: for example, group 17 elements are the halogens ; and group 18 are the noble gases. Also displayed are four simple rectangular areas or blocks associated with the filling of different atomic orbitals. The elements from atomic numbers 1 hydrogen to oganesson have all been discovered or synthesized, completing seven full rows of the periodic table.
