Properties of a metal

• What are the properties of a metal?
• Hardness
• Shininess
• Strength
• Conductivity
• Malleable
• Ductile
• May be magnetic
• High melting temperatures

6
Conductivity

• Able to easily transmit heat and electricity.

7
Malleable

• Able to pounded or rolled into shapes.

8
Ductile

• Able to be pulled out into a long wire.

9
Magnetic

• Attracted to magnets and can be made into a
  magnet.

10
Magnetic

• Attracted to magnets and can be made into a
  magnet.
• Magnet metals are iron, nickel and cobalt.

11
Chemical properties

• Chemical properties refers to the ease and speed
  of chemical reactions (bonds).

12
Chemical properties

• Chemical properties refers to the ease and speed
  of chemical reactions (bonds).
• Elements with few valence electrons react quickly
  and with many other elements.

13
Corrosion

• This is a chemical reaction with oxygen. The
  metal gradually flakes or wears away and becomes
  discolored.

14
Corrosion

• This is a chemical reaction with oxygen. The
  metal gradually flakes or wears away and becomes
  discolored. This is called oxidation.

15
Alloys

• A mixture of metals, which means they are
  physically together in the same place but not
  chemically combined.

16
Alloys

• A mixture of metals, which means they are
  physically together in the same place but not
  chemically combined.
• Examples of alloys
• Bronze copper tin

17
Alloys

• A mixture of metals, which means they are
  physically together in the same place but not
  chemically combined.
• Examples of alloys
• Bronze copper tin
• Brass copper zinc

18
