Ruthenium is a chemical element; it has symbol Ru and atomic number 44. It is a rare transition metal belonging to the platinum group of the periodic table. Like the other metals of the platinum group, ruthenium is unreactive to most chemicals.

ruthenium (Ru), chemical element, one of the platinum metals of Groups 8–10 (VIIIb), Periods 5 and 6, of the periodic table, used as an alloying agent to harden platinum and palladium. Silver-gray ruthenium metal looks like platinum but is rarer, harder, and more brittle.

Ruthenium is one of the most effective hardeners for platinum and palladium, and is alloyed with these metals to make electrical contacts for severe wear resistance. It is used in some jewellery as an alloy with platinum. Ruthenium has no known biological role. Ruthenium (IV) oxide is highly toxic. Ruthenium is one of the rarest metals on Earth.

2020年1月28日 · Ruthenium or Ru is a hard, brittle, silvery-white transition metal that also belongs to the noble metals and platinum metals group in the periodic table. While it does not readily tarnish, the pure element can form a reactive oxide that can explode.

Ruthenium is a chemical element with symbol Ru and atomic number 44. Classified as a transition metal, Ruthenium is a solid at room temperature.

Ruthenium is a whitish silver transition metal. It belongs to the platinum group of metals and in the 8 th group of periodic table. Unlike the other members of the group that have two electrons in their outmost shell, ruthenium has only one valence electron.

2024年6月16日 · Ruthenium (Ru or atomic number 44) is a transition metal that belongs to the platinum group on the periodic table. It has remarkable hardness, resistance to corrosion, and versatility in various industrial applications.

2020年4月8日 · With the periodic table symbol Ru, atomic number 44, atomic mass of 101.07 g.mol-1, and electron configuration [Kr] 4d75s1, ruthenium is a very hard, brittle, silvery-white metal substance that is classified as a transition metal.

Ruthenium is a very rare, hard, lustrous, brittle, silvery-white metal that does not tarnish at room temperature. Typical of transition metals, ruthenium can exist in many oxidation states, its most common being the oxidation states II, III and IV. The metal is unaffected by air, water and acids.

What is Ruthenium. A transition metal, ruthenium (pronounced as roo-THE-nee-em) is denoted by the chemical symbol Ru [1]. Its abundance in the earth’s crust is estimated to be 1×10-7 % [19]. It is one of the precious metals, belonging to the platinum family that also includes rhodium, palladium, osmium, and iridium [20, 26]. Ru is often used ...
