Which of the following statements are correct?
A NaCl type is f.c.c. unit cells with corners and faces occupied by either cation or anion
In a face-centred cubic unit cell, the body centre is an octahedral void
In f. c. c. unit cell, octahedral and tetrahedral voids are equal
Tetrahedral voids = 2 × octahedral voids, is true for only c. c. p and h. c. p.
f c c has cations occupying corners and faces ,anions occupying body center and edge centers and vice versa
