The periodic table is a tabular arrangement of the chemical elements, ordered by their atomic number, electron configuration, and recurring chemical properties, whose adopted structure shows periodic trends.
Generally, within one row (period) the elements are metals on the left, and non-metals on the right, with the elements having similar chemical behaviours being placed in the same column.
Table rows are commonly called periods and columns are called groups. Six groups have accepted names as well as assigned numbers: for example, group 17 elements are halogens; and group 18 are noble gases.
