CHEMISTRY PLEASE PLEASE HELP ME 4. Apply Theories Apply the theory of metallic bonding lo explam
metals.
b.) ductility
5. Apply Theories Apply the theory of metallic bonding to explain why a metal horseshoe
bends but does not break when a blacksmith pounds it into shape with a hammer.
7. Relate Cause and Effect Why is it possible to bend metals but not ionic crystals?
8. Apply Concepts What two properties of metals make copper an excellent material for use
in electrical circuits? Explain.
9.
tify Which of the following choices lists properties that result from metallic bonding?
A luster, thermal conductivity, solubility
B malleability, solubility, density
C electrical conductivity, luster, brittleness
D thermal conductivity, ductility, malleability
10. Identify What is a valence electron?
A an electron in the highest occupied energy level of an atom
B an electron in the lowest occupied energy level of an atom
C a nonbonding electron
Dany electron of an atom
11. Explain In terms of valence electrons, why are the atoms in a piece of metal considered to
be cations even though no electrons have been lost?
