Zinc And Lead

Zinc Zn is a bluish-white lustrous metal that is brittle at room temperature, but malleable when heated. It has a low melting point 419.5 C and a moderately high specific gravity 7.13. Lead Pb is a soft, ductile, malleable, bluish-white metal with a low melting point 327.4 C and a high specific gravity 11.3. Zinc and lead minerals often occur together because, as elements, they ...
