Why are metals strong but ionic solids are brittle?
Metals have strong metallic bonding but ionic solids have weak ionic bonds.
Metals have stronger intermolecular forces than ionic compounds.
When force is applied, the like-charged ions in ionic solids line up and repel each other.
The electrostatic attraction between the positive metal ion and sea of delocalised electron is weaker in ionic solids than metals.
Materials can be classified by their chemical structures. Four common types of structure are ionic, simple molecular, giant molecular and metallic.
