'''Group 10''', numbered by current [[IUPAC]] style, is the [[Periodic table group|group]] of [[Chemical element|chemical elements]] in the [[periodic table]] that consists of [[nickel]] (Ni), [[palladium]] (Pd), [[platinum]] (Pt), and perhaps also the chemically uncharacterized [[darmstadtium]] (Ds). All are [[d-block]] [[Transition metal|transition metals]]. All known [[isotopes]] of darmstadtium are radioactive with short half-lives, and are not known to occur in nature; only minute quantities have been synthesized in laboratories.
Like other groups, the members of this group show patterns in [[electron configuration]], especially in the outermost shells, although for this group they are particularly weak, with palladium being an exceptional case. The relativistic stabilization of the 7s orbital is the explanation to the predicted electron configuration of darmstadtium, which, unusually for this group, conforms to that predicted by the [[Aufbau principle]].
