IGCSE Chemistry Topic Questions on Paper 4 Extended Theory, 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
