This document discusses metals and their properties. It defines metals as good conductors of heat and electricity that are malleable and ductile. It lists common metals like aluminum, copper, iron, and titanium. It also discusses non-metals and their differences from metals like lower melting points and being poor conductors. Finally, it outlines some common uses of metals like in jewelry, pans, and cables due to their conductive properties and outlines uses of non-metals like insulation.
