Fourteen of these structures including “orthorhombic” were proposed by Auguste Bravais (“brah-vay”). For 10 points each,
[10e] Name these repeating arrays of points that define the arrangement of atoms in a crystal.
ANSWER: lattices [accept crystal lattices or Bravais lattices]
[10h] The intersection of planes with crystalline lattices can be described by these indices. To calculate these indices, one takes the reciprocal of the plane’s intercepts with the coordinate axes.
ANSWER: Miller indices
[10m] The body-centered cubic unit cell, which can build a Bravais (“brah-vay”) lattice, contains this many atoms. Contributions from this many ions are depicted in a Born-Haber Cycle.
