Atomic Structure and the Periodic Table

You must have heard about the periodic table, right? As you may know, it is an effective tool that can help you organise the elements according to their chemical properties. Additionally, it also highlights how both periodic table and atomic models have evolved over time and how new evidences are discovered. You can use our free paraphrasing tool for writing in your assignment without worrying about plagiarism. This table contains atoms that further contain protons, neutrons and electrons. So, simply explained, the periodic table is a chart that has all the elements arranged according to increasing atomic number.This topic is further divided into:

• • Size and mass of atoms
  • The model of the atom
  • The periodic table and its groups
  • Properties of transition metals

Bonding, Structure, and the Properties Of Matter

In this topic, you study how metal elements react with non-metal elements and how a compound is formed. Also, you explore the properties of matter and how it forms bonds with chemical elements. In this, you just need to study how atomic bonds are formed and how they affect the properties of substances. Moreover, you also get to explore modern materials like nanomaterials and polymers.The topics covered under this are:

• • The three states of matter and their symbols
  • Properties of metals and alloys
  • Sizes of particles and their properties
  • Ionic, Covalent & Metallic Bond

Quantitative Chemistry

Here, as the name suggests, you need to focus on the masses of the elements and calculate the different masses that are in reactions. Additionally, you need to work on concentrations of solutions and understand what products can be made from a given reaction. You also study and explore different chemical reactions and formulas and how they are determined. Generally, 20% of the questions are calculation-based, focusing less on the theory part.It has the below-mentioned sub-topics:

• • Amount of substance and gas volume
  • Chemical measurements and amounts
  • Relative formula mass
  • Yield and atom economy of chemical reactions

Chemical Changes

This topic is all about chemical reactions and the metal's reactions. You also learn how new substances form when original chemicals react. Simply put, it shows the relationship between products and the reactants and carries out possible results. Here, you must learn about all seven types of chemical changes and their properties. So, it covers the below sub-topics:

• • Strong and weak acids
  • Extraction of metals and reduction
  • Neutralisation of acids and salt production
  • The pH scale and neutralisation

Energy Changes

In this topic, you study the chemical reactions that involve changes due to changes in the formation of bonds. There are two major types of reactions: exothermic reaction, in which energy is released, and endothermic reaction, in which heat energy is infused. So, in this, there are the sub-topics mentioned below that you must know to do a chemistry revision.

• • Reaction profiles
  • Exothermic and endothermic reactions
  • Chemical cells and fuel cells
  • The energy change of the reaction

The Rate and Extent of Chemical Change

Do you know that chemical reactions depend upon five significant factors? Yes, i.e., pressure, temperature, surface area concentration, and the presence of a catalyst. So, here, you need to explore how these factors can be manipulated to slow down or speed up the reaction. It includes the rate of reactions and also reversible reactions that may reach a dynamic equilibrium. So, it covers the subtopics below.

• • Rate of Reaction
  • Collision theory and activation energy
  • Reversible reactions and dynamic equilibrium
  • Calculating rates of reactions

Organic Chemistry

Here, you need to focus on organic Chemistry that covers the properties, structure, composition, reactions, carbon-containing compounds, fossil fuels, and more. Also, it covers different types of organic compounds like alkenes, polymers, alkanes, and alcohols. You focus on how the chemist uses organic compounds to make new products and materials. It includes the below sub-topics:

• • Properties of hydrocarbons
  • Reactions of Alkenes & Alcohols
  • Structure and formulae of alkenes
  • Synthetic and naturally occurring polymers

Chemical Analysis

In chemical analysis, you must identify specific chemicals. To do this, you have two major methods, which are instrumental and manual methods. It covers formulations, pure substances, chromatography, and how particular gases and ions work. So, it has the following topics:

• • Identification of ions
  • Identification of common gases
  • Purity, formulations & chromatography
  • Methods of identifying ions

Chemistry of the Atmosphere

As the name suggests, in this, you look at how Earth's atmosphere changes. It covers the process of photosynthesis, combustion, and respiration. Moreover, it also covers the impact of humans on the environmental atmosphere. If you find this topic challenging, you can just take an online exam help from us for an effortless experience. So, the topics included in this are:

• • Carbon footprint
  • CO2 & CH4 as greenhouse gases
  • Atmospheric pollutants
  • Composition and evolution of the Earth's atmosphere

Using Resources

Using resources is the final topic covered in GCSE Chemistry. It is a crucial branch that focuses on how chemists develop ways of producing drinking water, fertilisers, and other such vital products. Moreover, it also covers the disposal of products at the end of its life. So, it includes the below important topics:

• • Sustainable development
  • Life cycle assessment
  • Global reserves & potable water
  • The Haber process

So, this was it; you must have understood that all topics come under GCSE chemistry. All of these topics are taken from the updated syllabus for the year 2025 to help you out with Chemistry revision.
