4. A metal sulfate compound is made of a metal bonded to a sulfate group. The sulphate group is -SO 4 . A metal carbonate compound is made of a metal bonded to a carbonate group. The carbonate group is -CO 3 . A metal nitrate compound is made of a metal bonded to a nitrate group. The nitrate group is -NO 3 .

5. Compounds including oxygen Naming metal and non-metal compounds Sulfates, carbonates and nitrates Naming compounds

6. Compounds have different names depending on the combination of elements they contain. Naming metal and non-metal compounds

7. Naming a compound made from a metal and a non-metal: Naming metal and non-metal compounds magnesium + oxygen → If there are two elements bonding together, the end of the non-metal name is changed to -ide. metal name magnesium non-metal name ox ide

8. The table shows examples of different non-metals in compounds. They all end in -ide. Naming metal and non-metal compounds metal name non-metal name compound name silver oxide lithium chloride potassium fluoride silver bromide zinc iodide iron sulfide oxygen silver chlorine lithium fluorine potassium bromine silver iodine zinc sulfur iron

10. What is the compound copper chloride made from? Naming metal and non-metal compounds copper and fluorine copper and chloride copper and chlorine copper and oxygen copper chloride

11. Complete the missing information: Naming metal and non-metal compounds metal name non-metal name compound name silver oxygen silver oxide iron oxygen sodium sulfide iodine potassium _______ zinc chloride sodium fluoride

12. Naming metal and non-metal compounds metal name non-metal name compound name silver oxygen silver oxide iron oxygen sodium sulfide iodine potassium zinc chloride sodium fluoride potassium sodium sulfur chlorine fluorine iron oxide sodium iodide zinc

13. Compounds including oxygen Naming metal and non-metal compounds Sulfates, carbonates and nitrates Naming compounds

14. When a metal reacts to form a compound with a non-metal and oxygen, the non-metal part of the compound name has the ending -ate . Compounds including a non-metal and oxygen iron + sulfur + oxygen → metal name iron non-metal name sulf ate oxygen

15. Compounds including oxygen metal name non-metal name also includes compound name iron sulfur oxygen iron sulfate lithium carbon oxygen lithium carbonate potassium nitrogen oxygen potassium nitrate The table shows examples of compounds formed when the reaction includes a metal, non-metal and oxygen.

16. Which compound(s) contain oxygen? Compounds including oxygen sulfides sulfates carbonates nitrates

17. If a metal, non-metal and oxygen react and make a compound, the name of the compound will end in -ide. Compounds including oxygen When a metal and oxygen are involved in a reaction the compound ends in -ate. When a metal, non-metal and oxygen are involved in a reaction the compound ends in -ate.

18. What would be the name of the compound formed when calcium, carbon and oxygen react together? Compounds including oxygen calcium carbonite calcium carbonate carbonate calcium carbon calcate marble chips and chalk are made from calcium carbonate

19. Compounds including oxygen Complete the table. metal name non-metal name also includes Name of the compound iron nitrogen oxygen magnesium oxygen nickel bromine oxygen copper chlorine oxygen potassium sulfate lithium carbonate

20. Compounds including oxygen Complete the table. metal name non-metal name also includes Name of the compound iron nitrogen oxygen magnesium oxygen nickel bromine oxygen copper chlorine oxygen potassium sulfate lithium carbonate iron nitrate magnesium oxide nickel bromate copper chloride sulfur potassium oxygen carbon lithium

21. Compounds including oxygen Naming metal and non-metal compounds Sulfates, carbonates and nitrates Naming compounds

22. Sulfates, carbonates and nitrates are examples of compounds ending in -ate. Sulfates, carbonates and nitrates compound ending general name sulfate metal sulfate carbonate metal carbonate nitrate metal nitrate

23. Sulfate, carbonates and nitrates can be represented by symbols. Sulfates, carbonates and nitrates compound ending compound ending symbol atoms involved sulfate SO₄ 1 × sulfur, 4 × oxygen carbonate CO 3 1 × carbon, 3 × oxygen nitrate NO 3 1 × nitrogen, 3 × oxygen copper sulfate would be written CuSO₄ calcium carbonate would be written CaCO 3 potassium nitrate would be written KNO 3

24. Na is the symbol for sodium. Name the compound NaNO 3 . Sulfates, carbonates and nitrates sodium sulfate sodium nitrate sodium carbonate NaNO 3

25. What ending would the formula of zinc sulfate have? Sulfates, carbonates and nitrates SO 4 CO 3 NO 3

26. Sulfates, carbonates and nitrates Izzy is writing a set of rules for naming compounds that contain oxygen. Complete or correct her ideas. CuSO 4 is the formula for __________ When a metal reacts to form an element with a non-metal and oxygen, the compound has a name that starts with -ate. compound ending compound ending symbol sulfate CO 3 nitrate __________ has the formula PbCO 3 .

27. Sulfates, carbonates and nitrates Izzy is writing a set of rules for naming compounds that contain oxygen. Complete or correct her ideas. CuSO 4 is the formula for When a metal reacts to form with a non-metal and oxygen, the compound has a name that -ate. compound ending compound ending symbol sulfate CO 3 nitrate has the formula PbCO 3 . a compound ends in Lead carbonate copper sulfate. carbonate SO₄ NO 3

28. Match up the formula to the compound’s name. Sulfates, carbonates and nitrates nitrate sulfate carbonate lead sodium potassium copper barium PbSO 4 NaNO 3 BaSO 4 CuCO 3 KNO 3

29. Sulfates, carbonates and nitrates lead sodium nitrate sulfate potassium carbonate copper barium PbSO 4 NaNO 3 BaSO 4 CuCO 3 KNO 3

30. The name of a simple metal – non-metal compound ends in -ide to indicate bonding has occurred. The name of a simple metal - non-metal compound ends in -ate if oxygen is also involved. Compounds of metals bonded to -CO₃ are called metal carbonates. Compounds of metals bonded to -SO₄ are called metal sulfates. Compounds of metals bonded to -NO₃ are called metal nitrates.
