8. Physical Properties of Metals Metals are: –Efficient conductors of heat and electricity. –Malleable (Can be hammered into thin sheets). –Ductile (Can be pulled into wires). –Lustrous (shiny). –Tend to lose electrons and form cations. Examples are: Na, Cu, Au, Ag, & Fe.

9. Metalloids Substances with the properties of both metals and nonmetals. Also called semimetals Lie along the zigzag line between metals and nonmetals The seven metalloids are: –B, Si, Ge, As, Sb, Te, At.

10. Physical Properties of Nonmetals Nonmetals are: –Nonconductors of heat and electricity (insulators). –Not malleable, but are brittle. –Not ductile. –Dull and without a luster. –Tend to gain electrons to form anions. Examples are: H, He, N, O, S, & P.
