Classification of Elements

Classification of Elements and Periodicity in Properties

The periodic table is a tabular arrangement of the chemical elements, ordered by their atomic number, electron configurations, and recurring chemical properties. This ordering shows periodic trends, such as elements with similar behaviour in the same column. It also shows four rectangular blocks with some approximately similar chemical properties. In general, within one row (period) the elements are metals on the left, and non-metals on the right.

The rows of the table are called periods; the columns are called groups. Six groups have generally accepted names as well as numbers: for example, group 17 elements are the halogens; and group 18, the noble gases.
