Naming compounds
I can name compounds from their chemical formulae.

Lesson details
Key learning points
- The name of a simple metal–non-metal compound ends '-ide' to indicate bonding has occurred.
- Some common groups of compounds are metal carbonates, metal sulfates and metal nitrates.
- Compounds of metal atoms bonded to -CO₃ are called metal carbonates.
- Compounds of metal atoms bonded to -SO₄ are called metal sulfates.
- Compounds of metal atoms bonded to -NO₃ are called metal nitrates.
Common misconception
Students often forget to change the non-metal name to either -ide or -ate.
Emphasise when the non-metal reacts with a metal it changes its name to -ide. It is -ate if the non-metal is also bonded to oxygen.
Keywords
Metal sulfate - Compound is made of a metal bonded to a sulfate group. The sulphate group is -SO₄.
Metal carbonate - Compound is made of a metal bonded to a carbonate group. The carbonate group is -CO₃.
Metal nitrate - Compound is made of a metal bonded to a nitrate group. The nitrate group is -NO₃.
