   3. They have low electrical conductivity.
2. In metallic bonding, what is the role of the “sea of electrons”?
   1. It generates heat.
   2. It provides electrical conductivity.
   3. It forms covalent bonds.
   4. It generates electricity.
3. At room temperature, most metals are either a:

   2. Gas
   3. Liquid
4. What does malleable mean?
   1. Look shiny
   2. Join easily
   3. Break easily
   4. Able to be shaped
5. Why do metals conduct?
   1. The electrons are held tightly within the lattice.
