Raney nickel contains an alloy of nickel and this element. An atom of this element bonded to four hydrogen atoms and accompanied by a lithium counterion forms a very strong reducing agent.
Raney nickel contains an alloy of nickel and this element. An atom of this element bonded to four hydrogen atoms and accompanied by a lithium counterion forms a very strong reducing agent. This element's trichloride is used as a Lewis acid in the first step of the Friedel-Crafts reaction. This element typically forms 3+ ions by losing 1 electron from its 3-p orbital and 2 electrons from its 3-s orbital. It is found along with sodium and fluorine in cryolite. This element is purified in the Bayer  process by smelting the ore bauxite. For 10 points, name this metal from which most kitchen foil is made.
