2.28 understand that metals can be arranged in a reactivity series based on the reactions of the metals and their compounds: potassium, sodium, lithium, calcium, magnesium, aluminium, zinc, iron, copper, silver and gold

2.28 •4, 3, 2, 2 - in terms of their order of reactivity 

         •Polly Said Look Cynthia Marry Alan (CARBON) Zinc I (HYDROGEN) Can See Goodness 

                   •carbon is included because this helps to explain what happens in the extraction of iron in a blast furnace

                             •anything below hydrogen won’t react with dilute acids

        •Potassium, Sodium, Calcium, Lithium, Calcium, Magnesium, Aluminium, Carbon, Zinc, Iron, Hydrogen, Copper, Silver, Gold

*up to red (i.e blue) reacts with water; up to hydrogen reacts with acid; up to yellow reacts with oxygen
