Don't show this again! Periodic Table of Elements. The periodic table of the chemical elements displays the organizing principles of matter. The table is a tabular depiction of the chemical elements and their characteristics. Russian chemist Dmitri Mendeleev is generally credited with the invention of the periodic table.
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 (columns) have names as well as numbers: for example, group 17 elements are the halogens; and group 18, the noble gases. The periodic table can be used to derive relationships between the properties of the elements, and predict the properties of new elements yet to be discovered or synthesized.
