Read each question carefully and provide your best answer. Show all your work where applicable.
1. Which model best describes the nature of metallic bonding?
Ionic lattice model
Covalent network model
Electron sea model
Hydrogen bond model
2. Which property of metals is directly explained by the delocalized electrons in metallic bonding?
High melting point
Brittleness
Electrical conductivity
Low density
3. In metallic bonding, valence electrons are and are not associated with any single atom. They are free to move throughout the entire metallic structure.
4. The ability of metals to be hammered into thin sheets is called .
5. The strong electrostatic attraction between the positive metal ions and the delocalized electrons is responsible for the melting points of metals.
6. Metals are generally good conductors of heat but poor conductors of electricity.
True
False
7. The 'sea of electrons' model explains why metals are ductile and malleable.
True
False
8. Describe the 'sea of electrons' model of metallic bonding. How does this model account for the characteristic properties of metals?
9. Explain why metals are good conductors of heat and electricity.
