* Composition: A 2p coin is made of copper and nickel.
* Mixtures: Mixtures are combinations of substances where each substance retains its own properties. In a 2p coin, the copper and nickel are physically combined but not chemically bonded. You can still identify the properties of copper and nickel in the coin.
* Compounds: Compounds are formed when two or more elements chemically combine in a fixed ratio. The resulting compound has entirely different properties than the original elements.
Therefore, the 2p coin is a mixture of copper and nickel.
