8.76 Using circles, draw regular two-dimensional arrangements that demonstrate low packing efficiency and high packing efficieny.
An amorphous solid can sometimes be converted to a crystalline solid by a process called annealing. Annealing consists of heating the substance to a temperature just below the melting point of the crystalline form and then cooling it slowly. Explain why this process helps produce a crystalline solid.

Thallium(I) iodide crystallizes with the same structure a CsCl. The edge length of the Unit cell of TlI is 4.20. Calculate the ionic radius of TI+. (The ionic radius of I is 2.16 .)
8.97 The doping of semiconductors can be done with enough precision to tune the size of the band gap in the material. Generally, in order to have a larger band gap, the dopant should be smaller than the main material. If you are a materials engineer and need a semiconductor that has lower conductivity thin pure silicon, what clement or elements could you use as your dopant? (You do not want either an n- or a p- type material) Explain your reasoning.

The interhalogen compound BrF3 is a volatile, straw-colored liquid. The compound exhibits appreciable electrical conductivity because of autoionization (“solv” refers to BrF3 as the solvent): 2 BrF31l2 ∆ BrF2 +1solv2 + BrF4- 1solv2 The electrical conductivity of BrF3 decreases with increasing temperature. Is the autoionization process exothermic or endothermic?
