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 ...
Ruthenium trichloride. The highest known ruthenium halide is the hexafluoride, a dark brown solid that melts at 54 °C.It hydrolyzes violently upon contact with water and easily disproportionates to form a mixture of lower ruthenium fluorides, releasing fluorine gas.
Naturally occurring ruthenium (44 Ru) is composed of seven stable isotopes (of which two may in the future be found radioactive). Additionally, 27 radioactive isotopes have been discovered. Of these radioisotopes, the most stable are 106 Ru, with a half-life of 373.59 days; 103 Ru, with a half-life of 39.26 days and 97 Ru, with a half-life of 2 ...
Most definitions of the term 'refractory metals' list the extraordinarily high melting point as a key requirement for inclusion. By one definition, a melting point above 4,000 °F (2,200 °C) is necessary to qualify, which includes iridium , osmium , niobium , molybdenum , tantalum , tungsten , rhenium , rhodium , ruthenium and hafnium .
