nikkeliryhmän

Nikkeliryhmä, also known as the nickel group, is a collection of chemical elements in the periodic table characterized by their similar properties and atomic structures. These elements are located in group 10, periods 4 through 6, and include nickel (Ni), palladium (Pd), platinum (Pt), and sometimes other elements like roentgenium (Rg), although the latter are not well-characterized or naturally occurring.

Nickel is a lustrous, silvery-white metal widely used in stainless steel production, coinage, and plating due to its corrosion resistance and durability. Palladium and platinum are precious metals with significant industrial applications, notably in catalytic converters, electronics, jewelry, and investment.

Elements within the nikkeliryhmä share several general characteristics. They tend to have similar electron configurations, specifically a filled inner shell and outer d-electrons that contribute to their chemical behavior. These elements often exhibit high melting points and are resistant to corrosion. Their chemical reactivity varies, with platinum and palladium being relatively inert, while nickel shows more noticeable reactivity, especially in forming various oxidation states.

The nikkeliryhmä elements are primarily obtained through mining and refining of natural mineral deposits. Due to their physical and chemical properties, they are essential in various technological and industrial applications, including catalysis, electronics, and alloy production.

Overall, the nikkeliryhmä represents an important group of transition metals known for their durability, resistance to corrosion, and diverse industrial uses.
