  • metals higher up
    • more reactive
    • oxidise easily
  • Very reactive metals and acid 

    . Produce lots of hydrogen
    . fizz vigorously
  • Metal+Metal +water>metalhydroxide+ water -> metal hydroxide +hydrogen hydrogen
  • Metal+Metal +steam>metaloxide+steam —>metal oxide +hydrogenhydrogen
  • Most metals extracted ores found in the earths crust
  • Unreactive metals are found in the earths crust uncombined
  • Metal displacement
    more reactive metals oxidised
    least reactive gains electron
