A mineral having the formula crystallizes in ccp lattice with atoms occupying the lattice points. Pick out the correct statements of the following
View answer and explanation
Correct option: A
occupancy of tetrahedral voids, C.N. of
Option A (100 % occupancy of tetrahedral voids, C.N. of B=4) is correct because in a ccp lattice with A atoms at lattice points, there are 4 A atoms per unit cell, requiring 8 B atoms to satisfy the AB2 formula. This means all 8 tetrahedral voids are occupied, and the coordination number of B in a tetrahedral void is 4.
