Round 11: Tossup 2

Reagents containing this metal are coupled with an organohalide in the Kumada reaction. Generally, (-5[1])this metal is always present in Hauser bases, which can form a Schlenk equilibrium with another class of compounds that contain this element. This element and calcium can be extracted from dolomite. This metal is used (15[1]-5[1])to reduce titanium tetrachloride in the (*) Kroll process. (-5[1])Along with an organic group and a halogen, Grignard reagents possess (10[1])this element. (10[1])An ion of this metal appears (10[1])at the center of chlorophyll's porphyrin ring. Rocks rich in iron and this element are called mafic. For 10 points, name this second lightest alkaline earth metal with symbol Mg. (10[1])■END■ (10[1])
