      Rows in the table represent the periods and get longer as the atomic numbers increase. The number of electrons increase from left to right across the table. There are eighteen groups represented by columns in the table; these groups have chemical features in common and have the same number of electrons in the outer orbit of the atoms.

      The Periodic Table is one of the greatest inventions in the history of man. It allows scientists to predict physical and chemical properties of the elements. Dimitri Mendeleev (a Russian scientist) and Robert Mosley (a British chemist) put together this table in the late 1800’s based on properties of the elements known at the time.
