| 31. | "' Rhenium pentachloride "'is an inorganic compound of chlorine and rhenium.
|
| 32. | This compound was first prepared in 1933, a few years after the discovery of rhenium.
|
| 33. | The coordination number of 9 in this complex is the highest known for any rhenium complex.
|
| 34. | "' Rhenium heptafluoride "'is the compound with the formula ReF 7.
|
| 35. | These elements are vanadium, rubidium, indium, lanthanum, europium, rhenium and lutetium.
|
| 36. | Rhenium and tungsten hexafluorides are used for chemical vapor deposition of thin metal films onto semiconductors.
|
| 37. | However, recent analysis indicated the presence of rhenium ( element 75 ), not element 113.
|
| 38. | Refractory elements such as rhenium and ruthenium can be added to the alloy to improve creep strength.
|
| 39. | The chemical properties of this silvery gray, crystalline transition metal are intermediate between rhenium and manganese.
|
| 40. | A discredited rhenium sulfide known as " zappinite " does not appear to be valid.
