• Iron is a solid.
• Oxygen is a gas.
• Iron reacts with oxygen in the air to form a new compound called iron oxide.
• During the reaction, the atoms of iron and oxygen combine together.
• Iron oxide is a solid. It can be seen on the surface of the iron wool.
• Because the oxygen has added to the iron, the iron wool is heavier than at the start.
