IGCSE Chemistry: a Bunsen burner with a blue flame, a walnut rack holding three tinted test tubes of coral-red, amber and teal liquid, a conical flask of teal solution, a white dish of copper-blue crystals, a five-sphere molecule model, a five-block pH colour card and a brass-bladed steel spatula.

Explain reactions through particles and bonding, then strengthen calculations and practical responses.

  • Explain chemical observations through particles, structure, bonding and periodic patterns
  • Build reliable equations and calculations from stoichiometric relationships and units
  • Connect inorganic and organic reactions through reagents, conditions, evidence and products
  • Explain experimental choices and distinguish measurement limitations from chemical limitations

Course highlights

Explain observations from particles, structure and bonding Use a microscopic model to explain properties and reactions instead of recalling disconnected facts.
Select the scale
Move between particles, equations and macroscopic observations.
Connect structure and property
Relate bonding and arrangement to melting point, conductivity and reactivity.
Use periodic patterns
Explain trends through electronic structure and supporting evidence.
 Make equations and calculations reliable Build a repeatable path from balanced equations to moles, concentration, gas volume or yield.
Balance first
Establish formulae and stoichiometric ratios before calculating.
Track units and precision
Keep conversions and significant figures visible.
Interpret the result
Relate the number to amount, composition, purity or reaction performance.
 Build reaction networks instead of isolated facts Organise inorganic and organic chemistry through reagents, conditions, observations and products.
Group related reactions
Connect acids, redox, metals, salts and electrolysis through common principles.
Map organic changes
Follow homologous series and functional-group conversions.
Use evidence
Pair observations and tests with equations and conclusions.
 Reason through practical chemistry Explain why each apparatus, procedural and safety choice is needed, then evaluate the evidence obtained.
Plan the method
Choose apparatus, range, controls, separation and safety measures.
Record observations
Separate qualitative observation from chemical interpretation.
Evaluate limitations
Identify measurement, heat-loss, incomplete-reaction or contamination effects.
