Metals, Nonmetals, Metalloids Characteristics of a METAL Metallic or shiny luster Good conductors or heat and electricity Malleable – can be hammered into thin sheets Ductile – can be pulled into thin wire High density High melting point All are solids at room temperature (except Mercury) Easily lose electrons
Metals, Nonmetals, Metalloids Characteristics of a NONMETAL Dull in appearance Not malleable Not ductile Poor conductors of heat and electricity Many are gases at room temperature Solid nonmetals are usually brittle More than 97% of your body is made of nonmetals Tend to gain electrons
Metals, Nonmetals, Metalloids Characteristics of a METALLOIDS Have characteristics of metals and nonmetals All are solids at room temperature Some are shiny and some are dull Many are conductors, but not as good as metals
