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 face centered cubic (FCC) unit cell begins with a totally different layer, one that is packed much more efficiently. This figure shows the basic layer that will be repeated throughout the entire ...

It has a melting temperature of 660 C. 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 ...
