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 the periodic table of the elements, each numbered column is a group. In chemistry, a group (also known as a family) is a column of elements in the periodic table of the chemical elements. There are 18 numbered groups in the periodic table, and the f-block columns (between groups 3 and 4) are not numbered. The elements in a group have similar physical or chemical characteristics of the outermost electron shells of their atoms (i.e., the same core charge), as most chemical properties are dominated by the orbital location of the outermost electron.
