Answer:

The periodic table is a tabular display of chemical elements, arranged by atomic number, electron arrangement, and recurring chemical properties. The table structure reflects seasonal trends. The seven rows of the table, called stages, generally have metals on the left and not metals on the right. The columns, called groups, contain elements with similar chemical behavior. Six groups received names as well as assigned numbers: for example, the elements of group 17 were the halogens; and group 18 were the noble gases. Also shown are four simple rectangular areas or blocks associated with the filling of different atomic orbitals.
