1.2.1.2 The Periodic Table The periodic table is an organisation of elements arranged in increasing atomic number into a series of columns (groups) and rows (periods). The classification was chosen to emphasize the periodic nature of the chemical properties (http://www.webelements.com/; Figure...
There are 18 vertical columns, or groups, in the standard periodic table. At present, there are three versions of the periodic table, each with its own unique column headings, in wide use. The three formats are the old International Union of Pure and Applied Chemistry (IUPAC) table, the C...
