crystals - 2024 ACF Fall - Buzzpoints App

Question

These materials often adopt cubic structures, such as face-centered cubic, body-centered cubic, and simple cubic. For 10 points each:

[10e] Identify these materials contrasted with amorphous solids. These materials have a repeating lattice structure.

ANSWER: crystals [accept crystal lattice]

[10h] Another common cubic crystal structure is this element’s namesake “blende”, where each atom is coordinated to four atoms of the opposite element. It gets its name from a nickname of this element’s ore sphalerite.

ANSWER: zinc [or Zn; accept zincblende]

[10m] This element’s chloride also names a cubic crystal structure where each atom is coordinated to eight of the opposite atom. The hyperfine transition of this element’s 133 isotope is used to keep accurate time in atomic clocks.

ANSWER: cesium [or Cs; accept cesium chloride]
