  1. 1Metals are important in everyday life. In [blank_start]transport[blank_end], metals are used to make bicycles, cars, ships, trains, and aeroplanes.
    Metals have to be extracted from their raw materials, [blank_start]ores[blank_end].
    1. Atransport
    2. Bores
  2. 2Most metals in ores are [blank_start]chemically[blank_end] bonded to other elements in compounds. Many of these metals have been [blank_start]oxidised[blank_end] by air to form their [blank_start]oxides[blank_end]. Oxidation is the [blank_start]addition[blank_end] of oxygen, and involves a [blank_start]loss[blank_end] of electrons.
    1. Achemically
    2. Bphysically
    3. Coxidised
    4. Dreduced
    5. Eoxides
    6. Freductions
    7. Gaddition
    8. Hreduction
    9. Iloss
    10. Jgain
  3. 3Which of these statements are true?
    1. AOxidation is the gain of electrons, and is when oxygen is added. Reduction is the removal of oxygen, and involves the loss of electrons.
    2. BOxidation is the loss of electrons, and is when oxygen is added. Reduction is the removal of oxygen, and involves the gain of electrons.
  4. 4The reactivity series is a list of metals in order of their reactivity. The [blank_start]most[blank_end] reactive metals are at the top and the [blank_start]least[blank_end] reactive at the bottom. [blank_start]Potassium[blank_end] is at the top and [blank_start]gold[blank_end] is at the bottom.
    1. Amost
    2. Bleast
    3. CPotassium
    4. Dgold
  5. 5Most metals react vigorously with water.
    1. AVerdadero
    2. BFalso
  6. 6[blank_start]Copper[blank_end] doesn't react at all with water, and so can be used to make water pipes. [blank_start]Lead[blank_end] used to be used, until it was discovered that it was [blank_start]poisonous[blank_end]. Alkali metals react vigorously and give off [blank_start]hydrogen[blank_end] gas, leaving [blank_start]alkaline[blank_end] solutions.
    1. ACopper
    2. Bpotassium
    3. CLead
    4. DIron
    5. Epoisonous
    6. Fcontagious
    7. Ghydrogen
    8. HHydroxide
    9. Ialkaline
    10. Jacidic
  7. 7This is the order of reactivity:
    1) [blank_start]Potassium[blank_end]
    2) [blank_start]sodium[blank_end]
    3) [blank_start]lithium[blank_end]
    4) [blank_start]calcium[blank_end]
    5) [blank_start]magnesium[blank_end]
    6) [blank_start]aluminium[blank_end]
    7) [blank_start]zinc[blank_end]
    8) [blank_start]iron[blank_end]
    9) [blank_start]tin[blank_end]
    10) [blank_start]lead[blank_end]
    11) [blank_start]copper[blank_end]
    12) [blank_start]silver[blank_end]
    13) [blank_start]gold[blank_end]
    1. APotassium
    2. Bsodium
    3. Clithium
    4. Dcalcium
    5. Emagnesium
    6. Faluminium
    7. Gzinc
    8. Hiron
    9. Itin
    10. Jlead
    11. Kcopper
    12. Lsilver
    13. Mgold
  8. 8What gas is present when a metal reacts with water? How do you know?
    1. Ahydrogen gas. We know because there is a pop.
    2. BHydroxide gas. We know because there is a change in colour of the solution.
    3. Coxygen gas. We know because there is oxidation taking place.
  9. 93 ways to know if a reaction has taken place:
    1) a [blank_start]gas[blank_end] has formed - we know a [blank_start]gas[blank_end] has formed usually if there is bubbles.
    2) a [blank_start]colour[blank_end] change in the solution
    3) there is an [blank_start]odour[blank_end].
    1. Agas
    2. Bgas
    3. Ccolour
    4. Dodour
  10. 10hydrogen gas is given off if metals react with water/dilute acids.
    1. AVerdadero
    2. BFalso
