- It is used by divers when they need to breathe in the ocean or sea when they are diving and to reduce symptoms caused by diving deeper down.

• What are its properties? 
- It is a colourless, odourless and tasteless gas.
- It readily dissolves in cold water.

• Where is it found? 
- Oxygen is found naturally around the Earth.

• Does the non-metal need to be processed before it can be used? If so, how is this done? 
- Oxygen does not need to be processed as this is a natural source and it's not man-made.

• Are there any interesting facts about it? 
- Oxygen makes up around 21% of the Earth's atmosphere. It makes up around 50% of the Earth's crust, making it the most common element in the Earth.
- While you need oxygen to live, too much of it can kill you. This is because oxygen is an oxidant.
