Question

The crystal structure at STP of this metal is by far the most complex of all metallic elements, with 58 atoms per unit cell. A dark green liquid oxide of this metal explodes on contact with most organic compounds. Bleach oxidizes this metal from 3+ to 5+ in a reaction (15[1])catalyzed by a complex of this metal with a salen ligand, the Jacobsen (15[1])epoxidation. (-5[1])In one cluster, four atoms of this metal are successively (15[1])oxidized through states S0 to S4 to then (-5[1])oxidize (*) water. This metal’s dioxide is the most common cathode for alkaline batteries. A brown precipitate of this metal’s (-5[2])dioxide in Baeyer’s test indicates the presence of alkenes or alkynes, which an oxyanion (-5[1])of this metal converts to diols. For 10 points, name (10[1])this transition metal (-5[1])that has the 7+ oxidation (10[2])state (10[1])in (10[1])an oxyanion that is a powerful oxidizer (10[1])with a magenta color.
