How are reactive metals stored
WebThese are all very reactive metals and have to be stored out of contact with air to prevent their oxidation. Reactivity increases as you go down the Group. Lithium, sodium and potassium are stored in oil. (Lithium in fact floats on the oil, but there will be enough oil coating it to give it some protection.
