Answer» Answer: Metal Physical Properties: Lustrous (shiny) Good conductors of heat and electricity High melting point High density (heavy for their size) Malleable (can be hammered) Ductile (can be drawn into WIRES) Usually solid at room temperature(an exception is mercury) Opaque as a thin sheet (can't see through metals) Metals are SONOROUS or make a bell-like sound when struck Metal Chemical Properties: Have 1-3 electrons in the outer SHELL of each metal atom and LOSE electrons readily Corrode easily (e.g., damaged by oxidation such as tarnish or rust) Lose electrons easily Form oxides that are basic Fave lower electronegativities Nonmetal Physical Properties: Nonmetal Physical Properties:Not lustrous (dull appearance) Nonmetal Physical Properties:Not lustrous (dull appearance)Poor conductors of heat and electricity Nonmetal Physical Properties:Not lustrous (dull appearance)Poor conductors of heat and electricityNonductile solids Nonmetal Physical Properties:Not lustrous (dull appearance)Poor conductors of heat and electricityNonductile solidsBrittle solids Nonmetal Physical Properties:Not lustrous (dull appearance)Poor conductors of heat and electricityNonductile solidsBrittle solidsMay be solids, liquids or gases at room temperature Nonmetal Physical Properties:Not lustrous (dull appearance)Poor conductors of heat and electricityNonductile solidsBrittle solidsMay be solids, liquids or gases at room temperatureTransparent as a thin sheet Nonmetal Physical Properties:Not lustrous (dull appearance)Poor conductors of heat and electricityNonductile solidsBrittle solidsMay be solids, liquids or gases at room temperatureTransparent as a thin sheetNonmetals are not sonorous Nonmetal Physical Properties:Not lustrous (dull appearance)Poor conductors of heat and electricityNonductile solidsBrittle solidsMay be solids, liquids or gases at room temperatureTransparent as a thin sheetNonmetals are not sonorousNonmetal Chemical Properties: Nonmetal Physical Properties:Not lustrous (dull appearance)Poor conductors of heat and electricityNonductile solidsBrittle solidsMay be solids, liquids or gases at room temperatureTransparent as a thin sheetNonmetals are not sonorousNonmetal Chemical Properties:Usually have 4-8 electrons in their outer shell Nonmetal Physical Properties:Not lustrous (dull appearance)Poor conductors of heat and electricityNonductile solidsBrittle solidsMay be solids, liquids or gases at room temperatureTransparent as a thin sheetNonmetals are not sonorousNonmetal Chemical Properties:Usually have 4-8 electrons in their outer shellReadily gain or share valence electrons Nonmetal Physical Properties:Not lustrous (dull appearance)Poor conductors of heat and electricityNonductile solidsBrittle solidsMay be solids, liquids or gases at room temperatureTransparent as a thin sheetNonmetals are not sonorousNonmetal Chemical Properties:Usually have 4-8 electrons in their outer shellReadily gain or share valence electronsForm oxides that are acidic Nonmetal Physical Properties:Not lustrous (dull appearance)Poor conductors of heat and electricityNonductile solidsBrittle solidsMay be solids, liquids or gases at room temperatureTransparent as a thin sheetNonmetals are not sonorousNonmetal Chemical Properties:Usually have 4-8 electrons in their outer shellReadily gain or share valence electronsForm oxides that are acidicHave higher electronegativities Nonmetal Physical Properties:Not lustrous (dull appearance)Poor conductors of heat and electricityNonductile solidsBrittle solidsMay be solids, liquids or gases at room temperatureTransparent as a thin sheetNonmetals are not sonorousNonmetal Chemical Properties:Usually have 4-8 electrons in their outer shellReadily gain or share valence electronsForm oxides that are acidicHave higher electronegativitiesAre good oxidizing agents |
