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.

Metals

Properties of Metals appear to the left of the dark zig-zag line on the periodic table. Most metals are solid at room temperature.

Properties of Metals have metallic Luster shiny

Properties of Metals Ductile metals can be drawn into wire.

Properties of Metals Malleable metals can be hammered into sheets

Properties of Metals have a high also very dense. melting point. They are

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.

Nonmetals

Properties of Nonmetals occur to the right of 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 have nonmetallic luster; they tend to be dull.

Properties of Nonmetals Brittle Nonmetals are brittle so they break easily. This means nonmetals ARE NOT ductile or malleable.

Properties of Nonmetals have low density.

Properties of Nonmetals They also have a low melting point. This is why they are poor conductors of heat and electricity.

Metalloids

Properties of Metalloids can be found clustered around the dark zig-zag line that separates nonmetals. metals and

Properties of Metalloids (metal-like) have properties of both metals and nonmetals.

Properties of Metalloids are solids that can be shiny or dull.

Properties of Metalloids They are “okay” conductors of electricity and heat - better than nonmetals but not as well as metals.

Properties of Metalloids can be malleable and 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
