When and where was ruthenium discovered?

Ruthenium was discovered by Karl Karlovich Klaus, a Russian chemist, in 1844 while analyzing the residue of a sample of platinum ore obtained from the Ural mountains.

What is an interesting fact about ruthenium?

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.

How is ruthenium extracted?

Extraction. Ruthenium is obtained by separating it from other platinum metals, such as platinum, palladium, and osmium, with which it occurs. These metals are usually obtained as by-products during the refining of nickel metal. They are then separated from each other by a series of chemical reactions.

How does ruthenium occur in nature?

Ruthenium is generally found in ores with the other platinum group metals in the Ural Mountains and in North and South America. Small but commercially important quantities are also found in pentlandite extracted from Sudbury, Ontario and in pyroxenite deposits in South Africa.

Where is ruthenium on the periodic table?

Ruthenium with atomic number 44 was given the symbol Ru. It is included in group 8, period 5 and block d in modern periodic table and it is a member of the platinum group metals [5].

Can ruthenium burn forever?

It has been discovered that ruthenium is behind the never-ending fires in Southern Turkey. The flames, which are known as Yanartas, have been burning for over 2500 years. Scientists now believe that ruthenium is partly responsible for this as when it is combined with methane, it may burn virtually forever.

Why is ruthenium used in jewelry?

Ruthenium Plating silver jewelry is used to protect it from oxidation and also make it more durable and protect it from scratches. A ruthenium plated finish is similar in appearance to black nickel plating but with a much harder finish.

What products are made from ruthenium?

Ruthenium is most often combined with platinum or palladium in alloys. Electrical contacts, devices for measuring very high and very low temperatures, and medical instruments are often made from ruthenium alloys. Some types of jewelry are also made from ruthenium, though it is very expensive.

How many isotopes does ruthenium have?

Ruthenium consists of seven stable isotopes (⁹⁶Ru, ⁹⁸Ru, ⁹⁹Ru, ¹⁰⁰Ru, ¹⁰¹Ru, ¹⁰²Ru and ¹⁰⁴Ru).
