The Difference Between an Element Family and an Element Group By Anne Marie Helmenstine, Ph.D. The groups in the periodic table go by a variety of different names: Another way to group elements is based on their shared properties (in some cases, these groupings do not correspond to the c...

Group = number of electrons in(n−1)d subshell + number of electrons in (n)s subshell = 6+2 = 8 The number of the group is always 3 if the element is in the f block, Example: Cerium (58) belongs to the 3rd group in the periodic table. ...
