• They are difficult to break down into smaller
  pieces and changing their shape usually involves
  a lot of effort.

3
Conductors

  electricity.
• This is why they are used for pots and pans and
  in electrical circuits to carry the current.

4

• This is why they feel heavy and sink when placed
  in water.

5
Shiny and Silvery

  and gold.
• Some go dull over time.
• All metals are shiny when freshly cut.

6
High Melting and Boiling Points

• Most metals have very high melting and boiling
  points.
• They need to be heated to very high temperatures
  before they melt to become liquids.

7
Solids

• All metals are solids at room temperature.
• The only exception is mercury.
• Mercury is the only liquid under normal
  conditions.

8
Malleable

• This property means that metals can be hit
  without shattering.
• They can be hammered into shape, even when cold
  and not break into lots of small pieces.

9
Ductile

• This property means that metals can stretched
  very thinly without them breaking.
• This is why they can be drawn out into wires.

10
