Other questions in this quiz

2. What is ionic bonding?

  • Giant structure of transition metals.
  • Non-metals which share electrons.
  • A metal loses electrons to a non-metal and the electromagnetic forces attract the atoms together.
  • Metals in a lattice with delocalised electrons.

3. Electrolysis is:

  • A form of displacement with carbon.
  • Splitting up ionic compounds using electricity.
  • Generating electricity by burning fossil fuels.
  • Splitting radioactive nuclei.

4. Why are alloys stronger and harder than pure metals?

  • Different sized atoms disrupt the regular arrangement of atoms and so the layers cannot slide over each other.
  • Different types of free electrons repel each other and so keep the metal in a certain shape.
  • The added metal is harder than the original metal.
  • The atoms are now bigger so there is less room to move.

5. Which of these chemical symbols is incorrect?

  • Osmium - Os
  • Tungsten - Tg
  • Potassium - K
  • Silver - Ag
