Topic 9 The periodic table
Topic content
The periodic table is a method of classifying elements and its use to predict the properties of elements
9.1 Periodic trends
The change from metallic to non-metal across a period.
The relationship between group number, number of valency electrons and the metallic/non-metallic character

9.2 Group properties
Lithium, sodium and potassium in group 1 are relatively soft metals, showing a trend in melting point, density and reaction with water.

To predict properties of other elements in group 1 from given data
Chlorine, bromine and iodine in group VII are diatomic non-metals that show a trend in colour and know their reaction with other halide ions.

9.3 Transition elements
Transition elements are a collection of metals with high densities, high melting points, from coloured compounds and often act as catalysts (as the element or the compound)

9.4 Noble Gases
Noble gases are unreactive
They are useful because the are inert (unreactive), argon is used in lamps and helium is used for filling balloons.
