Properties of metals

Question 1

What are 3 properties for metals in general?

Answer 1

Strong, bendy and great conductors (heat and electricity)

Question 2

Where on the periodic table are the non-metals?

Answer 2

The far right

Question 3

Why are metals used in everyday uses?

Answer 3

1) Their strength and ‘bendability’ makes them useful for making things like bridges and car bodies.
2) Metals are ideal for anything where you need heat to transfer through it (saucepan bases)
3) Conductivity useful for electrical wires

Question 4

Some metals [ ] when exposed to air and water, so they need protected (painting). What is the issue with this?

Answer 4

Corrode

Corroded metals lose their strength and hardness

Question 5

What is metal fatigue?

Answer 5

Metals can get ‘tired’ when stresses and strains are repeatedly put on them over time. Leads to metals breaking - very dangerous

Question 6

Describe the properties of copper and uses

Answer 6

Good conductor of electricity - ideal for drawing out into electrical wires. It’s hard and string but can be bent. Doesn’t react with water.

Question 7

Describe the properties of Aluminium

Answer 7

Corrosion resistant, low density. Pure aluminium isn’t particularly strong, but it forms hard, strong alloys

Question 8

Describe the properties of Titanium

Answer 8

Low density metal. Very strong. Corrosion resistant

Question 9

Different metals are chosen for their use depending on their different [ ]

Answer 9

Properties

Question 10

What metal would you pick for plumbing? Why?

Answer 10

Criteria: Metal that could bend for pipes and tanks. Below hydrogen on the reactivity series so it doesn’t react with water.
Answer: Copper

Question 11

What metal would you pick for aeroplanes? Why?

Answer 11

Criteria: Strong metal, bent into shape, and light
Answer: Aluminium

Question 12

What metal would you pick for replacement hips? Why?

Answer 12

Criteria: Won’t corrode in contact with water. Light and not too bendy.
Answer: Titanium
