| 11. | The advent of transition metal catalyzed reagents provides alternative stereospecific methods for cyclopropanation.
|
| 12. | This will apply to octahedral coordination compounds of the transition metals.
|
| 13. | Octahedral MO 6 units are common in oxoanions of the larger transition metals.
|
| 14. | Hydrides in the transition metals and lanthanides are also typically polymeric covalent hydrides.
|
| 15. | In the formula, " M " stands for a transition metal.
|
| 16. | Lead is a post-transition metal and is relatively inert unless powdered.
|
| 17. | It is poorly soluble in water, like most transition metal carbonates.
|
| 18. | Phosphors are often transition metal compounds or rare earth compounds of various types.
|
| 19. | Most luminophores consist of conjugated pi systems or transition metal complexes.
|
| 20. | This soft gray post-transition metal is not found free in nature.
