rhe·ni·um

 (rē′nē-əm)
n. Symbol Re
A rare, dense, silvery-white metallic element with a very high melting point, extracted chiefly from molybdenite and used for electrical contacts, with tungsten for high-temperature thermocouples, and as a catalyst for refining hydrocarbon fuels. Atomic number 75; atomic weight 186.2; melting point 3,185°C; boiling point 5,596°C; specific gravity 20.8 (20°C); valence 1, 2, 3, 4, 5, 6, 7. See Periodic Table.

[From Latin Rhēnus, the Rhine.]

rhenium

(ˈriːnɪəm)
n
(Elements & Compounds) a dense silvery-white metallic element that has a high melting point. It occurs principally in gadolinite and molybdenite and is used, alloyed with tungsten or molybdenum, in high-temperature thermocouples. Symbol: Re; atomic no: 75; atomic wt: 186.207; valency: –1 or 1–7; relative density: 21.02; melting pt: 3186°C; boiling pt: 5596°C (est)
[C19: New Latin, from Rhēnus the Rhine]

rhe•ni•um

(ˈri ni əm)

n.
a rare metallic element of the manganese subgroup: used, because of its high melting point, in platinum-rhenium thermocouples. Symbol: Re; at. no.: 75; at. wt.: 186.2.
[< German Rhenium (1925) = Latin Rhēn(us) Rhine + -ium -ium2]
