A Group 5 element is one in the series of elements in group 5 (IUPAC style) in the periodic table, which consists of vanadium (V), niobium (Nb), tantalum (Ta), and dubnium (Db). Like other groups, the members of this family show patterns in its electron configuration, especially the outermost shells, though niobium curiously does not follow the trend:
Dubnium can only be produced in the laboratory, and does not exist in nature. [edit] Biological occurrencesOf the group 5 elements, only vanadium has been identified as playing a role in the biological chemistry of living systems: it is involved in some of the enzymes of higher organisms, and also, unusually, in the biochemistry of some marine tunicates.
