Aluminum Chloride has a formula of AlCl3 giving it 4 total atoms per molecule. Aluminum has a charge of +3 and Chlorine's most common charge is -1 meaning you need 3 chlorine for every 1 Aluminum to cancel the charges. Because of the chlorine, it would most likely be aqueous, or dissolved in a liquid. Aluminum Chloride has a formula of AlCl3 giving it 4 total atoms per molecule. Aluminum has a charge of +3 and Chlorine's most common charge is -1.
The unit cell, however, has to share each atom with the 8 other adjacent cells. Thus a unit cell gets 8 atoms only 1/8 of the time, hence 8*(1/8) = 1 atom per simple cubic unit cell. Similarly, FCC has the 1 atom from simple cubic, plus half of the 6 atoms on each of it's faces. Thus, FCC has 4 atoms per unit cell. On to the main question.
