Module 1 | The chemical Earth

Focus 3: Elements in Earth materials are present mostly as compounds because of interactions at the atomic level

Lesson 1 | Atomic structure

  • Identify that matter is made of particles that are continuously moving and interacting.

  • Describe qualitatively the energy levels of electrons in atoms.

  • Describe atoms in terms of mass number and atomic number.

Lesson 2 | Ions and ionic compounds

  • Describe the formation of ions in terms of atoms gaining or losing electrons.

  • Apply the Periodic Table to predict the ions formed by atoms of metals and non-metals.

  • Construct ionic equations showing metal and non-metal atoms forming ions.

  • Describe the formation of ionic compounds in terms of the attraction of ions of opposite charge.

  • Apply Lewis electron dot structures to:
    – the formation of ions
    – the electron sharing in some simple molecules

  • Construct formulae for compounds formed from:
    – ions

  • Analyse information by constructing or using models showing the structure of ionic compounds.

Lesson 3 | Molecules and covalent compounds

  • Describe molecules as particles which can move independently of each other.

  • Distinguish between molecules containing one atom (the noble gases) and molecules with more than one atom.

  • Describe the formation of covalent molecules in terms of sharing of electrons.

  • Apply Lewis electron dot structures to:
    – the electron sharing in some simple molecules

  • Construct formulae for compounds formed from:
    – atoms sharing electrons

  • Analyse information by constructing or using models showing the structure of covalent compounds.
