| 11. | All the metals are body-centered cubic except rhenium which is groups.
|
| 12. | Rhenium prefers to enter sulfides more readily than osmium.
|
| 13. | It does not contain rhenium or ruthenium and its nickel content is limited.
|
| 14. | The second known approved rhenium mineral is tarkianite, being also a sulfide.
|
| 15. | Byproducts of silver, rhenium, and palladium metals would also be recovered.
|
| 16. | This decay is a reason why rhenium-rich minerals are abnormally rich in.
|
| 17. | Unlike the case for rhenium, a trioxide has not been isolated for Tc.
|
| 18. | Rhenium can be dissolved in nitric or concentrated sulfuric acid to produce perrhenic acid.
|
| 19. | However, rhenium itself is an expensive metal.
|
| 20. | Rhenium heptafluoride is known but not the heptachloride.
