Directions: • Click “Slideshow” and “From Beginning” to view this presentation properly. • Make a 3 column chart and label the columns metals, Nonmetals, or Metalloids. • As you go through the presentation list the physical AND chemical properties of each.
Properties of Metals Metals appear to the left of the dark zig-zag line on the periodic table. Most metals are solidat room temperature.
Properties of Metals • Metals have shiny metallic Luster
Properties of Metals Ductile metals can be drawn into wire.
Properties of Metals Malleable metals can be hammered into sheets
Properties of Metals Metals have a high melting point. They are also very dense.
Properties of Metals Conductors Metals are good conductors of electricity and heat
Properties of Metals A chemical property of metal is its reaction with water and oxygen. This results in corrosion and rust.
Properties of Nonmetals Nonmetals occur to the rightof the dark zig-zag on the periodic table. Although Hydrogen is in family 1, it is also a nonmetal. Many nonmetals are gases at room temperature.
Properties of Nonmetals Nonmetals have nonmetallic luster; they tend to be dull.
Properties of Nonmetals Brittle Nonmetals are brittle so they breakeasily. This means nonmetals ARE NOT ductileormalleable.
Properties of Nonmetals Nonmetals have low density.
Properties of Nonmetals They also have a low melting point. This is why they are poor conductors of heatand electricity.
Properties of Metalloids Metalloids can be found clustered around the dark zig-zag line that separates metals and nonmetals.
Properties of Metalloids Metalloids (metal-like) have properties of both metals and nonmetals.
Properties of Metalloids Metalloids are solids that can be shiny or dull.
Properties of Metalloids They are “okay” conductors of electricityandheat - better than nonmetals but not as well as metals.
Properties of Metalloids Metalloids can be malleableand ductile but not always.
If a substance can be pulled into thin wires and is a dull tan color, what is it? metalloid
If you have a copper colored material that you can hammer into the shape of a coin what do you have? metal
If you find something that does not reflect light very well, keeps you warm, and will just tear if you stretch it, what do you have? nonmetal
