In an x-ray diffraction experiment for a single crystal, a diffraction peak for a specific plane can be obtained by having the incident beam making the proper angle with the plane of interest according to Bragg’s law .   For a single crystal of an FCC structure with a lattice parameter of 3A.  What is the interplanar spacing for a (111) planes?

It is common that cations transfer into interstitial sites since they are smaller in size compared to anions

DEVELOPMENTAL PERSPECTIVE ESSAY: (Write as much as you can! The more you write the more opportunity I have to give you points!)   Ah, c’est la vie. So is life. What is life?
