Zinc sulphide exists with two different crystal structures, the cubic zinc blend (top diagram) and the hexagonal Wurtzite (lower diagram). In the zinc blend structure the sulphur ions form an fcc ...

Since the stoichiometry of the salt is 2:1, we must fill all of the tetrahedral holes (the FCC structure gives four selenides, thus we need eight lithiums). will occupy the latice points that define ...

The electronic configuration of Aluminum is (Ne)(3s) 2 (3p) 1, and it has an atomic radius of 0.143 nm. At room temperature Aluminum has the face-centered-cubic crystal structure with a basis of one ...

Specifically, NaCl forms a “face-centered cubic” (FCC) lattice structure. In this configuration, each sodium ion is ...
