Three types of holes of the cubic closest packed structure are:
A)trigonal,tetrahedral and octahedral
B)tetrahedral,pyramidal and octahedral
C)tetrahedral,bipyramidal and octahedral
D)cubic,tetrahedral,and octahedral
E)tetragonal,tetrahedral and octahedral

Question

Quizplus · Accepted Answer

The cubic closest packed structure, also known as the face-centered cubic structure, has octahedral voids between every other layer of atoms and tetrahedral voids between every three layers of atoms. The trigonal and pyramidal holes are not present in this structure. Therefore, choice A is the correct option.
