In Chapter 4 We Were Able to Determine the Geometric

In Chapter 4 we were able to determine the geometric shape and resulting polarity of individual covalent molecules. In Chapter 5 we did not do this for ionic and metallic compounds. Why not?

A) Ionic and metallic compounds exist as three dimensional networks not as individual molecules.
B) The electrons in ionic compounds are transferred rather than being shared as in covalent compounds.
C) The difference in electronegativities of the bonded atoms is usually greater in ionic than in covalent and metallic compounds.
D) Covalent molecules are much larger than ionic compounds.
E) all of these
