Periodic patterns topic check

Practise G2 Chemistry periodic position, Groups 1, 17 and 18, metal reactivity and rust prevention, then check your use of reaction evidence.

Learning goals

Describe the Periodic Table as the elements arranged in order of increasing proton number
Relate an element's position in the Periodic Table to its proton number and electronic configuration
Explain why elements in the same group are similar using their electronic configurations
Describe the change from metallic to non-metallic character across a period
Relate the number of outer (valence) electrons to metallic or non-metallic character
Predict the properties of Group 1 and Group 17 elements from the Periodic Table
Describe lithium, sodium and potassium as soft, low-density metals with trends in melting point and reaction with water
Describe chlorine, bromine and iodine as diatomic non-metals with trends in colour, state and displacement of other halide ions
Explain why Group 18 elements are unreactive using their electronic configurations
Place common metals and hydrogen in order of reactivity from their reactions with water, steam and dilute hydrochloric acid
Deduce an order of reactivity from experimental results
Relate how easily a metal is extracted from its ore to its position in the reactivity series
Describe the conditions needed for iron to rust and how a barrier, such as paint, grease or plastic, prevents it
