Year 10 Science — Metals, non-metals and the reactivity series

Rank metals by the activity series, work out the ion a metal or non-metal forms from its electron shells, and say how each band of the series is won from its ore and kept from corroding.

Name: ________________________

  1. 1.Which pair of statements about ionic compounds matches what the chapter reports?

    • a) They melt at high temperatures and dissolve in water rather than in kerosene
    • b) They melt at high temperatures and dissolve in kerosene rather than in water
    • c) They melt at low temperatures and dissolve in water rather than in kerosene
    • d) They melt at low temperatures and dissolve in kerosene rather than in water

  2. 2.A cell for refining copper is drawn below, with the two plates hanging in the solution and the battery marked. Tap the plate the pure copper builds up on.

    Write the number of the part.

    12

  3. 3.Aluminium oxide reacts with acids and with bases alike, giving a salt and water either way. What one word describes an oxide that does this?

  4. 4.A metal does not react with cold water or hot water, but does react with steam to give an oxide and hydrogen. Which of these behaves that way?

    • a) Iron
    • b) Gold
    • c) Potassium
    • d) Calcium

  5. 5.A block of common salt does not conduct electricity, but the same salt melted or dissolved does. Why?

    • a) Water adds ions of its own to the solid
    • b) The solid has no ions until it is melted
    • c) The ions can move once the rigid solid structure is broken up
    • d) Melting turns the ions into electrons

  6. 6.Sort each metal by how the chapter says it is won from the earth.

    Groups: Found in the native state · Reduction using carbon · Electrolysis of the molten compound

    • Silver
    • Iron
    • Gold
    • Aluminium
    • Zinc
    • Sodium

  7. 7.Galvanised iron sheets are coated with a thin layer of which metal?

    • a) Aluminium
    • b) Tin
    • c) Chromium
    • d) Zinc

  8. 8.Match each description to the term the chapter gives it.

    • A mineral rich enough to extract the metal from at a profit
    • The soil and sand that come up with the ore
    • Heating a sulphide ore strongly in plenty of air
    • Heating a carbonate ore strongly in limited air
    • The insoluble leavings that settle under the anode
    • Gangue
    • Calcination
    • Roasting
    • Ore
    • Anode mud

Answer key — Year 10 Science — Metals, non-metals and the reactivity series

  1. 1. a) They melt at high temperatures and dissolve in water rather than in kerosene
  2. 2. 2 — The plate wired to the negative terminal
  3. 3. amphoteric
  4. 4. a) Iron
  5. 5. c) The ions can move once the rigid solid structure is broken up
  6. 6. Gold → Found in the native state; Silver → Found in the native state; Zinc → Reduction using carbon; Iron → Reduction using carbon; Sodium → Electrolysis of the molten compound; Aluminium → Electrolysis of the molten compound
  7. 7. d) Zinc
  8. 8. A mineral rich enough to extract the metal from at a profit → Ore; The soil and sand that come up with the ore → Gangue; Heating a sulphide ore strongly in plenty of air → Roasting; Heating a carbonate ore strongly in limited air → Calcination; The insoluble leavings that settle under the anode → Anode mud
