OCR Chemistry Bonding Revision Notes
Master OCR Chemistry Bonding using simple revision notes, key facts and practice questions — all generated by AI for your exam.
Bonding in chemistry refers to the interactions that hold atoms together in compounds. The main types of bonding include ionic, covalent, and metallic bonding, each with distinct characteristics and properties.
Key Concepts
- 1Ionic bonding involves the transfer of electrons from one atom to another.
- 2Covalent bonding involves the sharing of electron pairs between atoms.
- 3Metallic bonding consists of a 'sea of electrons' that are free to move around metal cations.
- 4Bonding affects the physical and chemical properties of substances.
- 5The type of bond formed depends on the elements involved and their electronegativities.
Simple Explanation
Bonding is how atoms stick together to form molecules and compounds. There are three main types: ionic bonds, where atoms transfer electrons; covalent bonds, where they share electrons; and metallic bonds, where electrons move freely among metal atoms. The type of bond affects how substances behave.
Memory Trick
“Remember 'ICE' for Ionic, Covalent, and Electron sea for Metallic bonding.”
