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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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