'''Group 10''', numbered by current [[IUPAC]] style, is the [[periodic table group|group]] of [[chemical element]]s in the [[periodic table]] that consists of [[nickel]] (Ni), [[palladium]] (Pd), [[platinum]] (Pt), and [[darmstadtium]] (Ds). All are [[d-block]] [[transition metal]]s. 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.
