Most of the elements on the Periodic Table are metals. Metals can be distinguished from non-metals by differences in their physical properties.
Which row correctly describes a metal?
A
B
C
D
Why are alloys harder than the pure metals from which they are made?
There are stronger bonds between the atoms
The atoms are all the same size
The layers of atoms are distorted
The properties of each element have combined
A sample of element Y is shiny and can be shaped by hammering.
Which row of the table corresponds to the properties of element Y?
A
B
C
D
The table shows some properties of four metals
Which of the four metals would be the most suitable for aircraft construction?
A
B
C
D
Which statement explains why alloys are tougher than pure metals?
The irregular sizes of the atoms distorts the regular arrangement in the metal structure, meaning more force is required to bend the metal
The irregular sizes of the atoms distorts the regular arrangement in the metal structure as the bonding is disrupted when the atoms are added
The regular sizes of the atoms distorts the irregular arrangement in the metal structure, meaning more force is required to bend the metal
A mixture of metals is tougher than a pure metal because a mixture has more intermolecular forces than a pure metal.
Which of these elements is a metal?
A
B
C
D
The diagram shows the experimental set-up a student used to investigate the composition of air. The student left the apparatus in the laboratory and observed that the water level had risen inside the test tube after one week.
Which statement explains why the water level rose?
Nitrogen monoxide was produced.
Iron oxide was produced.
The temperature of the water increased.
Sulfur dioxide was produced.
A student observed the reaction between copper(II) sulfate solution and zinc.
Which observations are correct for this reaction?
A
B
C
D

Which of the equations shows a reaction which would take place?
A
B
C
D
Small blocks of zinc are attached to ship hulls which are commonly made from steel, analloy of iron. This is done to prevent the hull from rusting.
Which statement explains this process?
Zinc is higher up on the reactivity series than iron so has a higher tendency to become reduced.
Zinc is lower down on the reactivity series than iron so has a higher tendency to become reduced.
Zinc is higher up on the reactivity series than iron so has a higher tendency to become oxidised.
Zinc is lower down on the reactivity series than iron so has a higher tendency to become oxidised.
Many metals can be extracted from their ores by heating the metal oxide with carbon.
Which of these metals can’t be extracted using carbon?
Zinc
Copper
Aluminium
Iron
The blast furnace is used to extract iron from haematite.
The haematite contains silica as an impurity.
What is used to react with the impurity and remove it?
Carbon
Calcium oxide
Carbon dioxide
Oxygen
Iron is extracted from hematite, Fe2O3, in a blast furnace. Limestone is also added to the furnace.
What is the purpose of the limestone?
To remove impurities from the iron ore
To heat up the blast furnace
To reduce the hematite
To neutralise acidic gases
In a blast furnace, iron (III) oxide is converted into iron and carbon monoxide isconverted into carbon dioxide, as shown in the equation:
Fe2O3 + 3 CO → 2 Fe + 3 CO2
What happens to each of these reactants?
Iron (III) oxide is reduced and carbon monoxide is oxidised.
Iron (III) oxide is oxidised and carbon monoxide is reduced.
Both iron (III) oxide and carbon monoxide are oxidised.
Both iron (III) oxide and carbon monoxide are reduced.
Which statement about the extraction of iron from its ore is
not correct?
Iron can be extracted by reduction with carbon
Iron is easier to extract than zinc
Iron is easier to extract than copper
Iron is extracted from the ore, hematite
Tin is less reactive than iron and the metal is extracted from its ore cassiterite, SnO. Which of the following statements are correct?
