"Group 8" redirects here. For the Swedish organization, see Group 8 (Sweden).

For "Group VIII", the rightmost group on the Periodic Table, see noble gas.

A Group 8 element is one in the series of elements in group 8 (IUPAC style) in the periodic table, which consists of the transition metals iron (Fe), ruthenium (Ru), osmium (Os) and hassium (Hs).

Like other groups, the members of this family show patterns in its electron configuration, especially the outermost shells though ruthenium curiously does not follow the trend:

All of these elements are classed in Group 8 because their valence shells hold eight electrons. Hassium can only be produced in the laboratory and has not been found in nature.
