Lesson Title: Today we are learning about
What are ionic compounds?
Remember to check for PROGRESS
Focus on Knowledge, Skills and Understanding
Success Criteria: You will show your learning by...
  1. An ionic compound is a giant structure of ions.
  2. Ionic compounds are held together by strong electrostatic forces of attraction between oppositely charged ions.
  3. These forces act in all directions in the lattice: this is called ionic bonding.
  4. The structure of sodium chloride can be represented in the following forms: ball and stick giant lattice and charged ion ionic lattice.
  5. Students should be able to deduce that a compound is ionic from a diagram of its structure in one of the specified forms
  6. Students should be able to describe the limitations of using dot and cross, ball and stick, two and three-dimensional diagrams to represent a giant ionic structure.
  7. Students should be able to work out the empirical formula of an ionic compound from a given model or diagram that shows the ions in the structure.
  8. Students should be familiar with the structure of sodium chloride but do not need to know the structures of other ionic compounds.

Keywords:
  • Ball and stick model: is a molecular model of a chemical substance which is to display both the three-dimensional position of the atoms and the bonds between them (1)
  • Lattice: a regular repeated three-dimensional arrangement of atoms, ions, or molecules in a metal or other crystalline solid. (1)
  • Electrostatic attraction: the phenomenon where a negatively charged atom or molecule is attracted to a positively charged atom or molecule (1)
  • Ionic compound: is a chemical compound composed of ions held together by electrostatic forces termed ionic bonding (1)

AFL/Key Questions:
  1. What is an ionic compound?
    A giant structure of ions
  2. What do we call the attraction between oppositely charged ions?
    Electrostatic attraction
  3. Describe the structure of a giant ionic lattice.
    It is a 'lattice' because the arrangement is a regular one and 'giant' because the arrangement is repeated many times with large numbers of ions.
  4. What two models can be used to represent giant ionic structures?
    Ball and stick and charged ion ionic lattice
  5. Give a limitation of each the ball and stick model and charged ion ionic lattice models for representing ionic bonds.
    Ball and stick model: - The ions are actually packed closer together - Gives a false image of bond direction when is only electrostatic attraction Charged ion ionic lattice model: - Difficult to see the arrangement of ions in 3D.
  6. Determine the empirical formulae of a compound given the ions: a) Na+ and N3- b) Al3+ and O2-
    a) Na3N b) Al2O3
  7. Draw out a dot cross diagram to show the ionic bond formed in the compound sodium chloride.
    The sodium ion has an electon pattern of (2,8) and is represented in square brackets with a + charge in the top right corner, as a consequence of having lost an electron from its outer shell. This is then placed next to the chloride ion, which has an electron pattern of (2,8,8) and is also represented in square bracket, but with a - charge in the top right corner, due to it gaining an electron.
