Key Topics with Explanatory Notes and Exam-Centered Definitions
Structure of the Atom
An atom is the smallest particle of an element that retains its chemical properties. Subatomic particles:
| Particle | Charge | Relative Mass | Position |
|---|---|---|---|
| Proton | +1 | 1 | Nucleus |
| Neutron | 0 | 1 | Nucleus |
| Electron | -1 | 1/1836 | Shells |
Atomic Number (Z): Number of protons. Mass Number (A): Protons + neutrons. Isotopes: Same Z, different A. Electronic Configuration: e.g., Sodium (2,8,1).

The Mole Concept and Stoichiometry
Mole (mol): Amount containing 6.02 × 10^23 particles (Avogadro's Constant). Relative Atomic Mass (Ar): Average mass relative to 1/12 carbon-12. Molar Mass: g/mol = Ar or Mr.
Formula: n = mass / molar mass. Molar Volume: 24 dm³ at RTP. Concentration: n = C × V (dm³).
Empirical Formula: Simplest ratio. Molecular Formula: Actual atoms.
Steps for Empirical Formula: 1. Masses/percentages to moles. 2. Simplest ratio.
Details: Mole Concept Notes | Calculate Moles Guide | Empirical Formulas
Measuring Purity
Purity: Absence of impurities. Methods: Melting/Boiling Points (pure have sharp points), Chromatography (separates mixtures), Titration (quantitative reaction), Gravimetric Analysis (weighing precipitate).
More: Purity Guide
Predicting Chemical Reactions
Use reactivity series, periodic trends, and equation balancing. For products: Identify reaction type (displacement, combination).
Guide: Predict Products | Elements Reactivity
Other Key Definitions (Concise, Exam-Centered)
- Electrolysis: Decomposition by electricity. Cathode: Reduction. Anode: Oxidation.
- Acid: Proton donor, pH <7. Base: Proton acceptor, pH >7.
- Homologous Series: Compounds with same functional group, gradual property change.
- Exothermic: Heat released, ΔH negative. Endothermic: Heat absorbed, ΔH positive.
- Catalyst: Lowers activation energy, unchanged.
- Reactivity Series: Metals arranged by reactivity (K > Na > Ca > Mg > Al > C > Zn > Fe > Sn > Pb > H > Cu > Ag > Au).
- Polymer: Long chain from monomers (e.g., polyethene from ethene).
- Greenhouse Gas: Traps heat (CO2, CH4).
