,For A-level Chemistry Paper 1 (Inorganic and Physical Chemistry), focus on the following key areas:
1. Atomic Structure and Periodicity:
Atomic Structure: Understand the structure of atoms, including the concepts of electrons, protons,
neutrons, isotopes, and electron configurations. Be able to determine the electronic configuration of
elements and use this to predict trends in the periodic table.
Periodic Table Trends: Study periodic trends such as atomic radius, ionization energy,
electronegativity, and electron affinity. Understand how these trends change across periods and down
groups.
2. Bonding and Structure:
Ionic Bonding: Understand the formation of ionic bonds, including the transfer of electrons, and how it
leads to the formation of ionic compounds.
Covalent Bonding: Study the formation of covalent bonds, including the concepts of shared electron
pairs, single, double, and triple bonds, and the use of Lewis structures.
3. Inorganic Chemistry:
Group 2 Elements (Alkaline Earth Metals): Focus on the physical and chemical properties of Group 2
elements, their reactions with water, oxygen, and acids, and the trends across the group.
Group 7 Elements (Halogens): Study the properties, trends, and reactions of halogens, as well as the
displacement reactions in halogen halides.
4. Thermodynamics:
Enthalpy: Understand the concept of enthalpy change and how to calculate the heat change in chemical
reactions. Study exothermic and endothermic reactions, and be able to calculate enthalpy changes using
Hess's Law.
5. Kinetics:
Reaction Rates: Understand the factors that affect the rate of reaction, including concentration,
temperature, surface area, and catalysts. Know how to use the rate equation and understand the
relationship between concentration and reaction rate.
6. Equilibria:
Dynamic Equilibrium: Understand the concept of dynamic equilibrium, Le Chatelier’s Principle, and
how changing concentration, pressure, or temperature affects equilibrium position.
Equilibrium Constants: Study the equilibrium constant expression, Kc, and how to calculate the
position of equilibrium using concentration data.
7. Redox Reactions:
Oxidation and Reduction: Understand the concepts of oxidation (loss of electrons) and reduction (gain
of electrons), and be able to identify oxidizing and reducing agents in reactions.
Electrochemical Cells: Study standard electrode potentials and how to use them to predict the
direction of redox reactions. Understand the working of galvanic cells and electrolysis
