metallic properties

Metals have high melting points and boiling points

the strong electrostatic forces of attraction between cations and the delocalised electrons hold the metallic lattice together

Metals are good conductors of electricity

the delocalised elctrons are attracted to the positive electrode in circuit

heat conductivity

conduct heat well because their free electrons quickly spread the heat. Electrons are free to move and so transmit this energy rapidly through the metal lattice

malleable

the delocalised electrons move alongside the cation lattice maintaining the strong bond

ductile

when a force causes layers of metal ions to move past each other, layers of ions are still. held together by the delocalised electrons between them

lustre

the free moving electrons (delocalised electrons) cause the metal lattice to reflect light and appear shiny

dense

Metals are dense because their atoms are packed tightly together.
