GCSE Chemistry Bonding Revision Notes
Master GCSE Chemistry Bonding using simple revision notes, key facts and practice questions — all generated by AI for your exam.
Bonding is the process by which atoms join together to form molecules and compounds. There are three main types of bonding: ionic, covalent, and metallic. Understanding these types helps explain the properties of different substances.
Key Concepts
- 1Ionic bonding involves the transfer of electrons from one atom to another.
- 2Covalent bonding involves the sharing of electrons between atoms.
- 3Metallic bonding involves a 'sea of electrons' that are free to move around, allowing metals to conduct electricity.
- 4The type of bonding affects the physical and chemical properties of substances.
- 5Bonding can be represented using diagrams such as Lewis structures.
Simple Explanation
Bonding is how atoms stick together to form everything around us. There are three main types: ionic bonding, where atoms give away or take electrons; covalent bonding, where they share electrons; and metallic bonding, where atoms share electrons in a way that allows them to move freely. Each type of bonding gives substances different properties, like hardness or conductivity.
