Properties of Metals

1
Properties of Metals

• This presentation shows the main properties of
  metals and their meanings.

2
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.

3
Shiny

• Most metals are silvery in colour, except copper
  and gold.
• Some go dull over time.
• All metals are shiny when freshly cut.

4
Conductors

• They are very good conductors of heat and
  electricity.
• This is why they are used for pots and pans and
  in electrical circuits to carry the current.

5
Ductile

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

6
Sonorous

• This property refers to the sound that metals
  make when they are hit.
• Metals make a ringing sound when they are struck.

Physical Properties of Non-Metals
8
Thermal Insulator

• Thermal insulators do not let heat pass through
  them.
• Wool is made out of non-metal elements like
  Carbon, Nitrogen, Oxygen and Sulphur

9
Brittle

• This means that it is likely to break if you drop
  it.

10
Electrical Insulator

• Non-Metals are poor electrical conductors.
• They therefore make good electrical insulators
  because they cannot conduct electricity
• The PVC coating on electrical wires is made of
  the non-metals Carbon, Hydrogen and Chlorine.

11
Dull

• Non-Metals do not have a shiny surface like
  metals.
• They are usually dull in appearance
