Delocalised electrons move freely throughout metal structure
Electrons not tied to specific atom, move freely in metal
Move in specific direction carrying electric charge through metal
Flow of delocalised electrons through the metal
Delocalised electrons gain energy, move faster, transfer energy quickly
Metallic bonding
Sea of electrons surrounds positive metal ions in regular pattern
Attraction between positive ions & delocalised electrons
Layers of atoms slide over each other without breaking bonds
Metals can be drawn into wires, bonds remain intact
Very high conductivity, used in wiring, relatively inexpensive
Lightweight, good conductor, used in power lines & cables
Better conductors than copper, don't corrode, used in high-end electronics
Quickly & evenly distribute heat, ideal for cooking
