Legend Transition metal Primordial element Synthetic
A Group 10 element is one in the series of elements in group 10 (IUPAC style) in the periodic table, which consists of the transition metals nickel (Ni), palladium (Pd), platinum (Pt), and darmstadtium (Ds).
Like other groups, the members of this family show patterns in its electron configuration, especially the outermost shells (though for this family it is particularly weak with palladium an exceptional case):
Z Element No. of electrons/shell 28 nickel 2, 8, 17, 1 46 palladium 2, 8, 18, 18 78 platinum 2, 8, 18, 32, 17, 1 110 darmstadtium 2, 8, 18, 32, 32, 17, 1
Group ten metals are white to light grey in color, and possess a high luster, a resistance to tarnish (oxidation) at STP, are highly ductile, and enter into oxidation states of +2 and +4, with +1 being seen in special conditions. The existence of a +3 state is debated, as the state could be an illusory state created by +2 and +4 states. Theory suggests that group 10 metals may produce a +6 oxidation state under precise conditions, but this remains to be proven conclusively in the laboratory.
The group ten metals share several uses. These include:
- Decorative purposes, in the form of jewelry and electroplating.
- Catalysts in a variety of chemical reactions.
- Metal Alloys.
- Electrical components, due to their predictable changes in electrical resistivity with regard to temperature.
- Superconductors, as components in alloys with other metals.
