3-41 Describe the structure of sodium chloride in the solid state.

3-26 Table 3-2 shows the following ions of copper: Cu+ and Cu2+. Do these violate the octet rule? Explain.

Occasionally, we will see an ionic compound that has a 1 counterion. (Later we will find that 1 counterions are often more than spectators and take an active role in many reactions.) a. What elements (other than H) on the periodic table are most likely to form a 1 anion? b. Draw a Lewis structure for the ionic compound NH4Cl (Hint. One atom is a 1 counterion).
