- Atoms join together to make compounds.
- When elements react, atoms combine with other atoms to make compounds.
- Compounds are represented by formulas.
- Atoms join together to make compounds.
- Held together by chemical bonds.
- Difficult to separate original elements out of a compound again.
- Chemical reaction is needed to do this.

- The opposite charges are called ionic bonding
- Sodium Chloride
- Magnesium Oxide
- Calcium Oxide
- Magnesium Oxide
- Sodium Chloride
- A compound formed from non-metals consists of molecules
- COVALENT BONDING
- Each atom shares an electron with another atom.
- COVALENT BONDING
- Carbon Monoxide

- COVALENT BONDING
- The compounds of an element is normally totally different from the properties of the original element.
- EXAMPLE: If Iron (magnetic metal) and Sulfur (yellow powder) react, the compound Iron Sulfide is formed, it is a dull grey solid lump, doesnt behave like sulfur or iron.
