ionic bonding

• giant lattice structure
• ionic bonding is the electrostatic forces of attraction between oppositely charged ions
• high melting points as as large amounts of energy needed to overcome the strong electrostatic forces of attraction
• very brittle as any dislocation leads to layers moving to simmilar charges which repel
• do not conduct electricity as solid as ions are not freely moving so need to be liquid
• soluble in only water as it is a polar solvent
