What is the importance of ruthenium?
Ruthenium compounds can be used in solar cells, which turn light energy into electrical energy. 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.
What makes ruthenium unique?
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.
Who was ruthenium discovered by?
Karl Ernst Claus
How did the element ruthenium get its name?
Word origin: The word ruthenium comes from Ruthenia, the Latin word for Russia. Discovery: Ruthenium’s discovery is generally credited to Karl Ernst Klaus in 1844. He called one of them ruthenium. In 1844, Klaus demonstrated that Osann’s ruthenium oxide was very impure and that the new metal was contained in the oxide.
Why is ruthenium used in jewelry?
A member of the platinum group of metals, this metal is not only rare it has some great properties for jewellery. Ruthenium is strong, extremely hard wearing and scratch resistant so it’s ideal for providing some striking finishes to silver jewellery.

Is pure ruthenium toxic?
Health effects of ruthenium All ruthenium compounds should be regarded as highly toxic and as carcinogenic. Compounds of ruthenium stain the skin very strongly. It seems that ingested ruthenium is retained strongly in bones. Ruthenium oxide, RuO4, is highly toxic and volatile, and to be avoided.

Where did the name ruthenium platinum come from?
Interesting Ruthenium Facts. Ruthenium was the last of the platinum group metals to be discovered. The element name comes from the Latin word ‘Ruthenia’. Ruthenia means Russia, which refers to the Ural Mountains of Russia, the original source of the platinum metal group ores.
Where did the ruthenium come from in aqua regia?
From the portion of crude platinum that is insoluble in aqua regia, Klaus obtained 6 grams of ruthenium. 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 hydroxides. It has four crystal modifications.
Who was the first person to isolate ruthenium?
Karl K. Klaus was the first to isolate ruthenium as a pure element. This was an involved process in which he first prepared the salt, ammonium chlororuthenate, (NH 4) 2 RuCl 6, and then isolated the metal from it in order to characterize it.
