Presentation Transcript

  1. Metal • An element with a distinctive set of physical properties: luster, good conductor of heat and electricity, malleability, and ductility.

  2. Nonmetal • An element that DOES NOT HAVE the physical properties of metals: dull luster, NOT good conductors of heat and electricity, NOT malleable, and NOT ductile.

  3. Metalloid • An element that has the appearance of a metal with some of the physical properties but not all of the physical properties of metals. • Gold vs Fool’s Gold

  4. Ductility • A material’s ability to be stretched into a wire

  5. Malleability • Capable of being flattened or shaped by pounding with a hammer

  6. Luster • The shine for the surface of a material (dull or shiny)

  7. Conductivity • The ability of a material to transfer heat or electricity. • Heat Conductivity • Electrical Conductivity

  8. Density • Density is a measure of how much mass is contained in a given unit volume (density = mass/volume). • One of the ways we can see density illustrated in everyday life is by looking at whether things float or sink in a liquid • If an object is less dense than the liquid it is placed in, it will float. If it is more dense, it will sink. This is why an anchor, which is very dense (lots of mass in a relatively small volume) sinks very quickly, while an inner tube (not much mass in a relatively large volume) floats and is very difficult to push underwater.
