reactivity series

• metal + water ->

  metal hydroxide + hydrogen
• sodium + water -> _____+_____

  sodium hydroxide + hydrogen
• metals react with ___ to produce ___ and _______


  acid to produce salt and hydrogen gas
• you can test for hydrogen gas by using the

  squeaky pop test
• the most reactive metals are the alkali metals lithium, sodium, potassium, rubidium, caesium and francium.
• rusting can be prevented using an anti-corrosion agent such as oil or grease.
• the squeaky pop test is when you put a burning splint near the top of a flask containing hydrogen gas, it will make a loud noise as the hydrogen burns.
• a metal that is more reactive than another will displace it from its compounds.
• metal + acid -> 


  salt + hydrogen
• lead + hydrochloric acid ->


  lead chloride + hydrogen
• metal + oxygen -> metal oxide
• reactivity is a scale and elements of low reactivity do not react as strongly with water, acid or oxygen
• if an element doesn’t react it is unreactive
• a more reactive metal will displace a metal lower down the reactivity series
