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.

Element Ruthenium (Ru), Group 8, Atomic Number 44, d-block, Mass 101.07. Sources, facts, uses, scarcity (SRI), podcasts, alchemical symbols, videos and images.

Ruthenium is a rare metal. It is ranked as the seventy-fourth most abundant element and is present around 100 parts per trillion in the Earth’s crust. The elemental or free form of ruthenium is very rare. Mostly, ruthenium is present in minerals and ores, especially with platinum, in …

2020年1月28日 · Ruthenium is a hard, brittle metal, commonly used in alloys and known for its corrosion resistance. Ruthenium's discovery dates back to 1844 by Karl Klaus, and its name comes from the Latin word for Russia. Ruthenium is toxic, with RuO4 being especially harmful, and it can stain or discolor the skin.

Ruthenium is a rare, precious metal that falls into the platinum metal category. Its sheen makes it look like platinum, but it doesn’t have the exact properties of its metallic cousin. It’s rarer and harder than platinum, yet at the same time, it’s also more brittle. Ruthenium also …

2013年5月29日 · Ruthenium is a member of the platinum group. It is a hard, white transition metal. It does not tarnish at room temperatures but oxidizes explosively. It can be attacked by halogens and...
