Reactions of Metals and Metal Compounds

Reactions of Metals and Metal Compounds

1. Properties

   • The characterstics of metals are called their properties.
     • Physical properties describe what aubstance is like.
     • Chemical properties describe how a substance reacts.

2. Non-Metals

   • The elements with the opposite properties to metals are called non-metals.

3. Salts

   • There are several ways of making salts.
     • Metal carbonates react with acids to make a salt, water and carbon dioxide.
     • Acids and alkalis react to form salts and water in neutralisation reactions.
     • Metal oxides react with acids to make a salt and water.
     • Metals react with acids to make a salt and hydrogen.

4. Metals

   • Metals are found combined with other substances in the Earth's crust in rocks called ores.
