This element's tetraethyl (TET-ruh-EE-thul) form used to be used as an anti-knock agent in gasoline, and it features with sulfuric acid in car batteries.
This element's tetraethyl (TET-ruh-EE-thul) form used to be used as an anti-knock agent in gasoline, and it features with sulfuric acid in car batteries. This element's major ore is its sulfide, galena (guh-LEEN-uh). Discoveries of this element's toxicity largely ended its presence in pipes, though it is still used in radiation shielding, as it has the highest atomic number of any stable element. For 10 points, name this element no longer used in paint, which has symbol Pb.
