Note:
IGCSE Chemistry Topic Questions on Paper 2 Multiple Choice, the Periodic Table
Concepts that the exam aims to test you on are:
9.1 The Periodic Table
Core
Describe the Periodic Table as a method of classifying elements and its use to predict properties of elements
9.2 Periodic trends
Core
- Describe the change from metallic to nonmetallic character across a period
Supplement
- Describe and explain the relationship between group number, number of outer-shell electrons and metallic/non-metallic character
9.3 Group properties
Core
- Describe lithium, sodium and potassium in Group I as a collection of relatively soft metals showing a trend in melting point, density and reaction with water
- Predict the properties of other elements in Group I, given data, where appropriate
- Describe the halogens, chlorine, bromine and iodine in Group VII, as a collection of diatomic non-metals showing a trend in colour and density and state their reaction with other halide ions
- Predict the properties of other elements in Group VII, given data where appropriate
Supplement
- Identify trends in groups, given information about the elements concerned
9.4 Transition elements
Core
- Describe the transition elements as a collection of metals having high densities, high melting points and forming coloured compounds, and which, as elements and compounds, often act as catalysts
Supplement
- Know that transition elements have variable oxidation states
9.5 Noble gases
Core
- Describe the noble gases, in Group VIII or 0, as being unreactive, monoatomic gases and explain this in terms of electronic structure
- State the uses of the noble gases in providing an inert atmosphere, i.e. argon in lamps, helium for filling balloons
