Exam Tips
- Always show working for calculations to gain method marks even if the final answer is incorrect
- Ensure all chemical equations are balanced and include state symbols where required
- Use the periodic table to identify block (s, p, d) and electronic configuration patterns
- Practice drawing 3D representations of molecules to demonstrate understanding of bond angles
- Memorize the characteristic flame colours and precipitation reactions for Group 2 and halide ions
- Always include state symbols in balanced equations unless otherwise specified
Common Mistakes to Avoid
- Incorrect conversion of units (e.g., cm³ to dm³ or temperature to Kelvin) in gas and titration calculations
- Failure to use the correct number of significant figures based on raw data
- Confusing intermolecular forces (hydrogen bonding, dipoles) with intramolecular covalent bonds
- Misidentifying the shape of molecules by ignoring lone pairs in VSEPR theory
- Incorrectly applying oxidation numbers in complex ions
