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

• 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.
