Copper iodide crystallizes in the zinc blende structure. The separation between nearest neighbor cations and anions is approximately 311 pm, and the melting point is 606 °C. Potassium chloride, by contrast, crystallizes in the rock salt structure. Even though the separation between nearest-neighbor cations and anions is greater (319 pm), the melting point of potassium chloride is higher (776 °C). Explain.
The elements xenon and gold both have solid-state structures consisting of cubic close-packing arrangements of atoms. Yet Xe melts at -112℃ and gold melts at 1064℃. Account for these greatly different melting points.
The figure below depicts a plane of atoms of radius R in some crystal. The plane intersects the atoms through their centers.
Therefore, we do not see atoms above and below this plane. We just see the circular cross-sections of the atoms that lie within the plane.
If we consider only simple cubic (SC), body-centered cubic (BCC), and face-centered cubic (FCC) crystal structures as options,
and we have no more information to rely on, what are the possible identities for the plane shown above?
Select the plane family and crystal structure pair that is consistent with the plane shown above (select two of the options below).
Hint: Convince yourself of your response by sketching out the corresponding unit cell faces that lie on this plane.
