3. A-100 QUESTION: What types of particles make up a ionic lattice
ANSWER: Cations and Anions

4. A-200 QUESTION: An ionic bond occurs between
ANSWER: A metal and non-metal

5. A-300 QUESTION: Can ionic compounds conduct electricity? EXPLAIN
ANSWER: Yes – in dissolved state because the ions are free to move

6. A-400
QUESTION: Explain why ionic compounds have the property of being brittle
ANSWER: When the crystal lattice is distorted, like charges are aligned and this causes the ions to repel causing the crystal to shatter

7. A-500
QUESTION: Explain why ionic compounds have high melting and boiling points
ANSWER: The electrostatic forces between the cations and ions are very strong

8. B-100
QUESTION: What is the balanced chemical formula between the atoms SODIUM and CHLORINE
ANSWER: NaCl

9. B-200
QUESTION: What is the balanced chemical formula between the atoms ALUMINIUM and OXYGEN
ANSWER: Al2O3

10. B-300
QUESTION: What is the balanced chemical formula between the molecules MAGNESIUM and HYDROXIDE
ANSWER: Mg(OH)2

11. B-400
QUESTION: What is the balanced chemical formula between the atoms SILVER and CHLORINE
ANSWER: AgCl3

12. B-500
QUESTION: What is the balanced chemical formula between the molecules COPPER (II) and SULPHATE
ANSWER: CuSO4

13. C-100 QUESTION: What types of particles make up a metallic lattice
ANSWER: Metal cations and delocalised electrons

14. C-200 QUESTION: What is a lattice?
ANSWER: A regular arrangement of particles

15. C-300 QUESTION: This diagram explains why metals are….? - +
ANSWER: good conductors of electricity

16. C-400
QUESTION: Why do metals have relative high melting and boiling temperatures?
ANSWER: Metallic bonds are strong and need a lot of energy to break them

17. C-500 QUESTION: Give one limitation of the metallic bonding model
ANSWER:
Not all metals are dense
Some have relatively low melting and boiling points
Metals conduct electricity to different degrees
It does not explain the magnetic nature of some metals

18. D-100 QUESTION: What are alloys?
ANSWER: Formed by mixing two metals or a metal with a small amount of a non-metal

19. D-200
QUESTION: Brass is made up of?
ANSWER: Copper and Zinc

20. D-300
QUESTION: what kind of alloy are made from elements that are similar in size?
Substitutional or Interstitial alloy
ANSWER: Substitutional

21. D-400 QUESTION: What is the Annealing process?
ANSWER: A metal is heated and allowed to cool slowly which makes the metal softer and more ductile

22. D-500
QUESTION: Which process involves heating a metal and cooling it quickly causing the metal to become more brittle?
ANSWER: Quenching

23. E-100 QUESTION: What is a covalent bond
ANSWER: when two or more atoms bond by sharing electrons

24. E-200 QUESTION: Covalent bonding usually occurs between…
ANSWER: non-metals

25. E-300 QUESTION: What are lone pairs?
ANSWER: outer shell electrons that are not involved in the forming of the bond (non-sharing electrons)

26. E-400
QUESTION: What kind of bond is formed when two pairs of electrons are shared between atoms?
ANSWER: Double bond

27. E-500
QUESTION: What kind of bond (single, double or triple) is seen in N2
ANSWER: triple
