PHONETICS

Rhenium is a silvery-white, heavy transition metal with an estimated average concentration of 1 part per billion (ppb) and is one of the rarest elements in the Earth’s crust and has the highest boiling point of any element, at 5,869 K (10,105 °F). Rhenium resembles manganese and technetium chemically and is obtained as a by-product of molybdenum and copper ore extraction and refinement.
