A-Level Chemistry Bonding Revision Notes
Master A-Level Chemistry Bonding using simple revision notes, key facts and practice questions — all generated by AI for your exam.
Bonding is the interaction between atoms that allows the formation of chemical compounds. Understanding the types of bonding—ionic, covalent, and metallic—is crucial for explaining the properties of substances.
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 is characterized by a 'sea of electrons' that are free to move.
- 4The type of bonding affects the physical and chemical properties of substances.
- 5Electronegativity plays a key role in determining bond type.
Simple Explanation
Bonding is how atoms stick together to form molecules and compounds. There are three main types of bonding: ionic, where atoms transfer electrons; covalent, where they share electrons; and metallic, where electrons are shared in a group. The type of bond affects how the substance behaves and its properties.
