Which one of the following schemes of ordering closed packed sheets of equal sized spheres does not generate close packed lattice:

Correct answer: C. ABAABBA

  • A. ABCBCA
  • B. ABACABAC
  • C. ABAABBA
  • D. ABCBCACBC

Explanation

The explanation for the correct option: ABBAABBA The method of organization A close-packed lattice is no produced by ABBAABBA of tightly stacked sheets of equal-sized spheres. It is because BB, AA, and BB represent the same stacked layer of sheets. ABAABBA schemes of ordering closed packed sheets of equal sized spheres does not generate close packed lattice.

About Crystal Lattice

A crystal lattice is the regular three-dimensional arrangement of particles in a crystalline solid. The content includes lattice points, unit cells, coordination number, packing patterns, and the differences among ionic, metallic, molecular and covalent network crystals, which should not be confused with amorphous solids.
