Metals - good conductors of heat and electricity, good reflectors of light, malleable, ductile, tend to lose electrons in forming bonds, low electronegativity, low ionization energy Nonmetals - poor conductors of heat and electricity, poor reflectors of light, soft or brittle, tend to gain electrons in forming bonds, high electronegativity, high ionization energy
Chemical Properties of Metals: 1) Usually have 1-3 electrons in their outer shell 2) Lose their valence electrons easily 3) Form oxides that are basic 4) Are good reducing agents 5) Have lower electronegativities Chemical Properties of non-Metals: 1) Usually have 4-8 electrons in their outer shell 2) Gain or share valence electrons easily 3) Form oxides that are acidic 4) Are good oxidizing agents 5) Have higher electronegativities Physical Properties of Metals: 1) Good electrical conductors and heat conductors 2) Malleable - can be beaten into thin sheets 3) Ductile - can be stretched into wire 4) Possess metallic luster 5) Opaque as thin sheet 6) Solid at room temperature (except Hg) Physical Properties of non-Metals: 1) Poor conductors of heat and electricity 2) Brittle - if a solid 3) Nonductile 4) Do not possess metallic luster 5) Transparent as a thin sheet 6) Solids, liquids or gases at room temperature
