Presentation transcript:

Do now! Can you NAME the following compounds? CuSO 4 LiNO 3 CaCO 3 KCl Fe 2 O 3

Last lesson Know how to explain the difference between an element and a compound Know that new materials are formed when atoms join together in different ways

Word equations zinc + sulphurzinc sulphide

Word equations magnesium + oxygenmagnesium oxide

Naming compounds

Metal and non-metal The name of the metal goes first, the nonmetal changes the ending to “ide” NaClSodium chloride MgSMagnesium Sulphide CuOCopper Oxide

Metal and Non-metal (including oxygen) The metal goes first, and the ending of the non-metal changes to “ate” CuSO 4 Copper sulphate MgSO 4 Magnesium sulphate Ca(NO 3 ) 2 Calcium Nitrate

Naming compounds Copy the following formulae and then write the name of each compound; 1.NaBr2. FeSO 4 3. KNO 3 4. FeS 5. AgNO 3 6. FeO 7. CsF8. Al 2 O 3 9. CoCl H 2 O

Today’s lesson Know how to work out the numbers of different atoms in a compound from its formula Know where to find metals and non-metals in the periodic table Formative assessment

Calcium Carbonate CaCO 3 (S)

Calcium Carbonate One atom of Calcium (Ca) CaCO 3 (S)

Calcium Carbonate One atom of Calcium (Ca) One atom of Carbon (C) CaCO 3 (S)

Calcium Carbonate One atom of Calcium (Ca) One atom of Carbon (C) Three atoms of Oxygen (O) CaCO 3 (S)

Nitric acid HNO 3 ?

One atom of hydrogen (H) One atom of nitrogen (N) 3 atoms of oxygen (O)

How many? H 2 SO 4 NH 3 H 2 O C 5 H 11 OH Ca(OH) 2

The Periodic table Can you stick the periodic table in and shade the metals, non-metals and metalloids different colours (with a key). Use you book (p59) to help you Can you then answer the questions on page 66 while Mr Porter comes round and talks to you about your work.
