Metallic Bonding
Metallic bonding occurs when positive metal ions are held together by electrostatic attraction to a sea of delocalised electrons. These pages separate the key ideas so that students can revise metallic structure and link it clearly to metal properties.
These pages cover electronegativity, ionic bonding and giant ionic lattices, metallic bonding, and covalent bonding with sigma and pi bonds, dative bonds and giant covalent structures.
They then cover the shapes and bond angles of molecules, polar molecules, and intermolecular forces with hydrogen bonding and the anomalous properties of water.
