  • C4 - Chemical Changes - The Reactivity Of Metals
    • Metal + Water ---> Metal Hydroxide + Hydrogen Bubbles
      • React With Water
        • Potassium
        • Sodium
        • Lithium
        • Calcium
        • Untitled
        • React Slowly With Hot Water
          • Magnesium
          • Zinc
          • Iron
        • Do Not React With Water
          • Copper, Silver & Gold
        • Example
          • Sodium + Water --------> Sodium Hydroxide + Hydrogen
    • Metal + Acid ----->Metal Salt +Hydrogen
      • Extremely Violent Reactions
        • Potassium, Sodium, Lithium
      • React with Acids to form salt +H2 gas
        • Calcium, Magnesium, Zinc, Iron
      • Do not react with acits
        • Copper, Silver. Gold
      • Metal tends to disappear or dissolve
      • Hydrogen in the form or bubbles or fizzing
      • EXAMPLE
        • Zinc + Hydrochloric Acid -----> Zinx Chloride +Hydrogen

    • Summary
      • HIGH REACTIVITY
        • Aluminium, Calcium, Sodium, Potassium (GROUPs 1, 2, 3 metals
      • Medium Reactivity
        • Copper, Iron, Tin, Zinc (More reactive transition Metals)
      • LOW REACTIVITY
        • Gold, Plantinum, Silver (Less Reactive Transition Metals
          • Used for Jewellery
      • Keywords
        • Displacement
          • When a more reactive element takes the compound away from a less reactive element, this commonly happens with the group 7 halogens and with metals
        • Extraction
          • Is a method used to obtain a pure metal (Usually from its ore)
        • Reactivity
          • Is how quickly and vigorously an element reacts. Low Reactivity elements will not react with many other substances and reactions will happen very quickly
        • Oxidation
          • When a Substance Gains Oxygen
    • Metal + Oxygen -------> Metal Oxide
      • Example
        • Magnesium + Oxygen -----> Magnesium Oxide
      • OXIDATION REACTION
      • React with Oxygen  very vigorously at room temperation
        • Potassium, Sodium, Lithium
      • React with Oxygen very slowly at room temperature or much faster when heated
        • Calcium, Magnesium, Zinc, Iron, Copper, SIlver
      • Metals that do not react with oxygen
        • Gold
