Year 9Fundamentals
Chemical Bonds & Structure
Understanding how atoms share or transfer electrons to form stable compounds.
Key Concepts
- Covalent Bonds: Non-metals share electrons to achieve a full outer shell.
- Ionic Bonds: Metals transfer electrons to non-metals, creating oppositely charged ions.
- Valence electrons determine an element’s reactivity and bonding capacity.
