What is an example of a very reactive metal?

• Platinum

• Lithium

• Silver

• Gold

Why does lithium have to be kept under oil?

• To prevent it from rusting

• To prevent it from getting dirty

• To prevent it from reacting with oxygen and moisture

• To prevent it from melting

What happens when lithium is added to a bowl of water?

• It turns into a solid mass

• It reacts quickly and produces hydrogen gas

• It sinks to the bottom and does not react

• It forms bubbles of oxygen

Why is platinum used in jewellery?

• Because it won't react with anything and stays shiny

• Because it is very reactive

• Because it is very heavy

• Because it is very cheap

What does calcium metal react with to produce bubbles of hydrogen?

• Water

• Carbon dioxide

Where is calcium carbonate found?

• In water

• In the air

• In metal compounds

• In many rocks used to construct buildings and roads

How do the different reactivities of metals influence their use?

• Unreactive metals can be used as uncombined elements

• Reactive metals are used mainly in compounds and have specialised uses

• Reactive metals can be used as uncombined elements

• Unreactive metals are used mainly in compounds
