Read each question carefully and answer to the best of your ability.
1. Which model best describes metallic bonding?
Ionic lattice model
Electron sea model
Covalent network model
Molecular orbital model
2. Which property of metals is a direct result of delocalized electrons?
Brittleness
High melting point
Electrical conductivity
Low density
3. In metallic bonding, valence electrons are , meaning they are not associated with any one particular atom.
4. The arrangement of positive metal ions in a metallic structure is often described as a .
5. The ability of metals to be drawn into wires is called .
6. Explain why metals are good conductors of heat and electricity.
7. Metals are generally hard and have high melting points due to the strong electrostatic forces between the positive ions and the delocalized electrons.
True
False
8. Draw a simple diagram illustrating the electron sea model of metallic bonding. Label the positive metal ions and the delocalized electrons.
