Rhenium: description
Rhenium is silvery white with a metallic lustre; its density is exceeded only by that of platinum, iridium, and osmium, and its melting point is exceeded only by that of tungsten and carbon. It has other useful properties. It is expensive but useful as a trace alloying agent.

Rhenium: history
Rhenium was discovered by Walter Noddack, Ida Tacke, Otto Berg in 1925 at Germany. Origin of name: from the Greek word "Rhenus" meaning river "Rhine".Rhenium: isotopes
Both Rhenium isotopes are used for medical purposes. Re-185 is used for the production of Re-186 which is used for bone pain palliation. Re-187 can be used for the production of Re-188 which is used for cancer therapy and restenosis, though most Re-188 is produced via W-186.
