reactivity series

• the reactivity series is a series of metals that are arranged in order of reactivity
• reactivity is determined how easily an electron is lost to form a positive ion
• the further away the electron is from the nucleus, the less electrostatic forces of attraction between the negative electron and positive proton
• when metals react with acid, hydrogen and salt is produced
• the speed of reaction is indicated by the rate at which hydrogen bubbles are produced
• the more reactive metal, the faster the reaction . metals like sodium and potassium react vigorously whereas metals like iron and zinc
• you can investigate reactivity by temperature change or colour change
• displacement reactions occur when a more reactive metal replaces the less reactive metal in a metal compound pushing it out
