2 What are the physical properties of metals? Most elements are metalsPhysical PropertiesSilver- grey in colorLuster (shininess)Solid at room temperatureGood conductors of heat and electricityWhat are the physical properties of metals?chromium
3 Metals Can be drawn into wire- ductile High density-heavy for their sizeHigh melting and boiling pointMalleable (can be hammered into thin sheets)May be magneticHave a characteristic sound when struck with an object (sonorous)Metalspotassium
4 What are the physical properties of nonmetals? Exist as solids, liquids, or gases at room temperatureDo not reflect light wellAre usually brittleCannot be hammered flatCannot be drawn into wireGenerally are soft and bend or break easilyDoesn’t have a characteristic sound when struck with an objectWhat are the physical properties of nonmetals?
5 Nonmetals Generally have low melting points Generally have low boiling pointsAre poor conductors of heat and electricityLow densities-light for their sizeAre not magneticNonmetalssulfur
6 Metalloids Physical Properties: Solids Can be shiny or dull Can be ductile or malleableCan be brittleConduct heat better than nonmetals, but not as well as metalsReactivity depends on the element with which they are reactingMelting and boiling point vary widelyDensity varies widely
8 Periodic Table The periodic table contains a zigzag line. Elements on both sides of the line have properties of both metals and nonmetals.Metals are located on the left side of the periodic table.Nonmetals are located on the right side of the table
