It is a rare transition metal belonging to the [[platinum group]] of the [[periodic table]]. Ruthenium is inert to most other chemicals and is usually found in ores with other platinum group metals in the Ural Mountains, North and South America. It is used in various industrial applications, including electrical contacts and [[electroplating]], due to its significant hardness, resistance to corrosion, and electrical conductivity.

==Properties==
Ruthenium is a hard, white metal that does not tarnish at room temperatures, maintaining its luster in most air and water conditions. It has a melting point of about 2334 degrees Celsius and a boiling point of about 4150 degrees Celsius. This metal exhibits a wide range of oxidation states, from -2 to +8, making it versatile for chemical reactions, especially in [[catalysis]].

==Occurrence==
Ruthenium is one of the least abundant elements in the Earth's crust. It is primarily obtained as a by-product of nickel and platinum mining. The extraction of ruthenium is complex, involving several chemical processes to isolate it from other platinum group metals.

==Applications==
Ruthenium has several important applications. In [[chemistry]], it serves as a catalyst for hydrogenation and other types of chemical reactions. In [[electronics]], it is used for making thick-film resistors and electrical contacts because of its good conductivity and durability. Ruthenium is also used in the chemical industry for its catalytic properties, particularly in the production of ammonia and acetic acid.

In recent years, ruthenium has found use in [[medicine]], particularly in cancer treatment. Compounds containing ruthenium show promise in chemotherapy, targeting cancer cells without harming healthy tissue. Additionally, its compounds are being studied for potential use in solar energy conversion and storage technologies.

==Health and Safety==
Ruthenium compounds can be hazardous to health if ingested or inhaled. They can cause irritation to the eyes, skin, and respiratory system. Safe handling practices and appropriate protective equipment are recommended when working with ruthenium compounds.

==Environmental Impact==
Ruthenium has a low environmental impact compared to many other metals. It is not considered a major environmental pollutant, partly because of its low abundance and limited mobility in the environment. However, like all metals, responsible disposal and recycling practices should be followed to minimize any potential environmental effects.
