2. Metallic Bond Bond that exists between metal atoms
Alloy – two or more different metal atoms bonded together

3. Electron Sea Model
Metal atoms give up valence electrons and form + ions
The released electrons move freely around the + metal ions

5. Properties of Metallic Bonds
Good conductors of electricity – free electrons
Malleable and ductile – not in rigid position so ions can be shaped and drawn into wires
Conduct heat because of free electrons
Lusterous – absorb and emit light in regular pattern due to free electrons
