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; the 14 f-block columns, between groups 2 and 3, are not numbered. The elements in a group have similar physical or chemical characteristics of the outermost electron.
Modern group names are numbers 1–18, with the 14 f-block columns remaining unnumbered (together making the 32 columns in the periodic table). Also, trivial names (like halogens) are common. In history, several sets of.
Two earlier group number systems exist: CAS () and old IUPAC. Both use ( or ) and letters A and B. Both systems agree on the numbers. The numbers indicate approximately the highest oxidation number of the elements in that.
