States of Matter and Particle Theory
This section covers the three states of matter and explains transitions between them using particle theory.
Vocabulary:
- Melting: Transition from solid to liquid
- Condensing: Transition from gas to liquid
- Evaporating: Transition from liquid to gas
Particle theory explains these transitions:
- As particles gain kinetic energy, their bonds break, allowing them to move more freely.
- The strength of forces of attraction affects a substance's melting and boiling points.
Highlight: Stronger forces of attraction between particles result in higher melting and boiling points.
Limitations of particle theory include:
- Atoms are not solid spheres as often depicted
- It doesn't consider intermolecular forces between different particles in different substances
Example: In chemical equations, , , , and represent solid, liquid, gas, and aqueous states, respectively.
Structure and Properties of Materials
This section explores how the structure of different materials affects their properties, which is crucial for understanding ionic and covalent bonding GCSE notes.
Ionic Compounds
The structure of ionic compounds influences their properties:
- High melting and boiling points due to strong electrostatic forces
- Unable to conduct electricity in solid state but can conduct when molten
Small Molecules
Small molecules with covalent bonds have distinct properties:
- Low melting and boiling points due to weak intermolecular forces
- Unable to conduct electricity due to lack of free ions or electrons
Polymers
Polymers have unique properties based on their structure:
- High melting and boiling points due to strong intermolecular forces
- Solid state at room temperature
Giant Covalent Structures
This section covers various giant covalent structures, which are important topics in GCSE Chemistry structure and bonding questions.
Alloys
Highlight: Alloys are harder than pure metals because they contain different sized atoms, preventing layers from sliding over each other easily.
Diamond
Properties of diamond include:
- Very hard structure due to each carbon atom forming 4 covalent bonds
- High melting and boiling points
- Does not conduct electricity
Graphite
Graphite has unique properties:
- High melting and boiling points
- Soft and slippery texture
- Conducts electricity and thermal energy
Example: Graphite's ability to conduct electricity is due to its structure, where only three of the four carbon electrons are used in bonds, leaving one free to move.
Graphene
Graphene is a modern material with interesting properties:
- One atom thick sheet of carbon atoms in hexagonal arrangement
- Excellent conductor of electricity
Fullerenes
Fullerenes have distinctive properties:
- Molecules of carbon shaped like closed tubes or hollow balls
- Large surface area, making them useful as catalysts and lubricants
- Can cage other molecules
- Low melting and boiling points
- Cannot conduct electricity or thermal energy
Nanotubes
Nanotubes are an important topic in modern materials science, with unique properties that make them valuable for various applications.
Highlight: The study of nanotubes and other nanomaterials is a growing field in chemistry and materials science, with potential applications in electronics, medicine, and energy storage.
Properties of Nanotubes
This page appears to begin discussing nanotube properties but is incomplete in the provided transcript.
Unit 2 - Bonding and Structure
Types of Bonding
Ionic Bonding
Ionic bonding is a crucial concept in GCSE Chemistry structure and bonding. It involves a strong electrostatic force of attraction between oppositely charged atoms.
Definition: Ionic bonding is a strong electrostatic force of attraction between two oppositely charged atoms.
Properties of ionic compounds include:
- High melting and boiling points due to strong electrostatic forces
- Ability to conduct electricity when molten
- Formation of a giant ionic lattice
Highlight: Ionic compounds form a giant ionic lattice where oppositely charged ions arrange in a regular pattern.
Covalent Bonding
Covalent bonding is another essential type of chemical bonding covered in GCSE bonding and structure chemistry notes.
Definition: Covalent bonding occurs when two non-metal atoms share a pair of electrons to obtain a full outer shell of electrons.
Properties of simple molecules with covalent bonds include:
- Low melting points due to weak intermolecular forces
- Inability to conduct electricity
- Existence as gases at room temperature
Metallic Bonding
Metallic bonding GCSE is a key topic for understanding the properties of metals.
Definition: Metallic bonding is a strong electrostatic force of attraction between positive metal ions and a sea of delocalized negative electrons.
Properties of metals include:
- Malleability due to layers that can slide over each other
- Good conductivity of heat and electricity
- High melting and boiling points
- Insolubility in water
- Solid state at room temperature
Example: The malleability of metals is explained by their layered structure, which allows the layers to slide over each other without breaking the metallic bonds.

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.
