Students will be able to
- describe how metals form giant lattice structures arranged in layers of regular patterns,
- describe the bonding in metals as a structure of positive ions surrounded by a sea of delocalized valence electrons,
- explain the term delocalized as referring to free electrons that can move around the metal lattice,
- describe how electrostatic interactions between the positive ions and delocalized valence electrons give rise to metallic bonding,
- describe how metallic bonding is responsible for the properties of metals, such as having high melting points and being malleable, ductile, and good conductors of heat and electricity,
- briefly explain what an alloy is (alloys are covered in a separate lesson).
