- metallic bonding and properties of metals
- giant metallic lattice
- positive metal ions in a cloud of delocalised e-
- layers can slide over each other
- malleable
- outer shell e- become delocalised
- positive metal ion attracted to delocalised e-
- the more delocalised e- the stronger the metal
- the stronger the bond, the higher the melting point
- melting point increases across a period and decreases down the group
- the stronger the bond, the higher the melting point
- e- can pass on kinetic energy
- good thermal conductors
- e- can carry charge
- good electrical conductors
- metallic bond strength depends on number of delocalised e- and size of metal ion
- the more delocalised e- the stronger the metal
- the stronger the bond, the higher the melting point
- melting point increases across a period and decreases down the group
- the stronger the bond, the higher the melting point
- the larger the atomic radius the weaker the attraction between (+) ion and delocalised e-
- the more delocalised e- the stronger the metal
- strong metallic bonds
- insoluble
- giant metallic lattice
