Rhenium is a chemical element with the symbol Re and atomic number 75. It is a transition metal of the third row, silver-gray, heavy in group 7 of the periodic table. With an estimated average concentration of 1 part per billion (ppb), rhenium is one of the rarest elements in the earth’s crust. Rhenium has the third-highest melting point and the second-highest boiling point of any element in 5903 K. Rhenium chemically recalls manganese and technetium and is obtained mainly as a byproduct of the extraction and refining of copper and molybdenum ores. Rhenium shows in its compounds a great variety of oxidation states ranging from -1 to +7.
