Properties of Metals.

Question 1

What side of the periodic table are non-metals on?

Answer 1

Right side.

Question 2

What are the basic properties of all metals?

Answer 2

• strong
• good at conducting heat
• good at conducting electricity.

Question 3

What are the properties of the centre block of metals?

Answer 3

• Strong and bendable ⇒ Good for building bridges and car bodies.
• ideal if you need heat to travel through e.g saucepan.
• conductivity makes it great for electrical wiring.

Question 4

What can happen to metals when they are stressed and strained?

Answer 4

This is known as metal fatigue and leads to metals breaking, which can be very dangerous e.g. planes.

Question 5

What are the specific properties of copper?

Answer 5

• good conductor of electricity
• hard and strong but can be bent
• doesn’t react with water.

Great for plumbing (pipes) as it is below hydrogen and does not react with water.

Question 6

When do some metals corrode?

Answer 6

When they are exposed to air and wtaer.

They need to be protected e.g. by painting .

If metals corrode they lose their strength.

Question 7

Whatare the specific properties of aluminium?

Answer 7

• corrosion-resistant
• low density

Pure aluminium isn’t particularly strong, but it forms hard, strong alloys.

Building planes because it is strong and can be bent to shape. Also needs to be lightweight.

Question 8

What are the specific properties of titanium?

Answer 8

• Low density metal
• very strong
• corrosion-resistant

Use: Replacement hips as it does not corrode when it comes into water. Also light and not to bendy.
