Mechanical Properties of matter: State, analyse and apply principles of atomic combinations: molecular structure

Subject outcome

Subject outcome 5.2: State, analyse and apply principles of atomic combinations: molecular structure

Learning outcomes

  • Use group properties of the periodic table to find the number of valence electrons and valency number of an element.
  • Use and draw Lewis diagrams and use octet rule to explain chemical bonds.
  • Define electronegativity of atoms and apply it to explain the polarity of chemical bonds.
  • Calculate oxidation number of atoms in molecules to explain their relative richness in electrons
  • Identify and molecular shapes and give molecular examples for the shapes.
    • Range: Molecular shapes are linear, angular, pyramidal, tetrahedral.
  • Identify polar and non-polar substances.
