Bonding, structure and properties
I can explain how bonding, structure and properties are linked together and answer related long answer questions.
Bonding, structure and properties
I can explain how bonding, structure and properties are linked together and answer related long answer questions.
Lesson details
Key learning points
- There are three different types of bonding (covalent, ionic, metallic).
- There are only two types of structure (simple and giant).
- The type of bonding and structure are what lead to properties of substances.
- Melting/boiling points are linked to intermolecular forces (simple) and bond strength (giant).
- Conductivity is linked to whether there are free moving charge carriers.
Common misconception
Ionic substances are binary compounds. Bonding and structure are the same thing. Only bonding influences properties.
As well as multiple ions in ionic substances, there can be polyatomic ions too. Bonding informs structure, and bonding and structure together influences properties.
Keywords
Bonding - Refers to the force of attraction between atoms or ions that hold them together.
Force of attraction - Refers to any force that causes two or more substances to come together.
Structure - Structures in chemistry are determined by the type of bonding and arrangement of atoms or ions.
Property - A feature or characteristic of a substance that can be used to classify it, or describe how it behaves.
Charge carrier - Particles that enable electrical conductivity, such as delocalised electrons or free–moving ions.

Electrons are shared between atoms.
Electrons are transferred, so charged ions, not atoms, are bonded.
Electrons are delocalised among a lattice of metal ions.
