5.1 reactivity series Flashcards
What are ores
rocks from which it is economical to extract the metals that they contain
what does oxidised mean
have oxygen added,
what has to be done to extract metal from their oxides
metal oxide must be reduced
What is the reactivity series
list of metals in order of their reactivity, with most reactive metals at the top and least at the bottom
how does the reactivity change when going down group 1
it increases
state the reactivity series

calcium
magnesium
aluminium
carbon
zinc
iron

potassium, sodium, lithium calcium reaction with water
fizz, give off hydrogen gas, leaving an alkaline solution of metal hydroxide
magnesium, aluminium, zinc, iron reaction with water
very slow reaction
tin, lead reaction with water
slight reaction with steam
copper, silver, gold reaction with water
no reaction, even with steam
potassium, sodium, lithium reaction with dilute acid
explode
calcium, magnesium, aluminium, zinc, iron reaction with dilute acid
fizz, giving off hydrogen gas and forming a salt
