Chemical bonding and structure
Ionic
Ions
An ion is a charged particle
Ions form from atoms or from groups of atom by loss or gain of one or more electron
Types
Cations
When an atom loses valence electrons
Metal (Group 1, 2 and 13)
Positive ion
Anions
When an atom gains electrons
Non-metal (Group 15, 16 and 17)
Negative ion
Transition metals
Group 14
Ionisation
Bonding
Structure
Ionic lattice
3-dimensional crystalline structure
Metallic
Covalent
Noble gases
Atoms have full outer shells of electron
Stable; have no tendency to react at all
