IB Chemistry 2.3.1 Metallic bonding Questions
Answer metallic bonding questions by linking the lattice model to malleability, conductivity and the physical properties used to identify a metal.
How this is tested
- explain malleability by non-directional metallic bonding, so cation layers slide without breaking the lattice
- distinguish K(s) from KCl(s): K conducts as a solid by delocalized e-, but solid KCl does not as ions are fixed
- identify a metallic substance from conductivity when solid and liquid, high mp, and typical insolubility in water
