Scientists have discovered that chemical element ruthenium (Ru) is fourth element to have unique magnetic properties (ferromagnetism) at room temperature.

• So far only three periodic table elements Iron (Fe), Cobalt (Co), and Nickel (Ni) have been found to be ferromagnetic at room temperature
• Ruthenium is chemical element with symbol Ru and atomic number 44
• .It is rare transition metal belonging to platinum group of periodic table.
• Like other metals of platinum group, it is inert to most other chemicals.
• It was discovered in 1844 by Russian-born scientist Karl Ernst. It named Ruthenium, after Latin name of Russia.
• Ruthenium is usually found as minor component of platinum ores.
• It is used in wear-resistant electrical contacts and thick-film resistors. Its minor application is in platinum alloys and as a chemistry catalyst.
