The reactivity series is a list of metals, sequenced based on how reactive they are to things like water or oxygen. The higher up the list you go, the more reactive the metals get.
Name all the metals in the reactivity series.
POTASSIUM
SODIUM
CALCIUM
MAGNESIUM
ALUMINIUM
ZINC
IRON
LEAD
COPPER
SILVER
GOLD
Metal + water =
Metal hydroxide + hydrogen
Metal + oxygen =
Metal oxide
DISPLACEMENT - give a definition
