The number of tetrahedral voids per unit cell in NaCl crystal is ..... – InterviewSolution

1.	The number of tetrahedral voids per unit cell in NaCl crystal is .........
Answer» 4 8 TWICE the number of octahedral voids. Four times the number of octahedral voids. Solution :NaCl has ccp structure. Hence, number of NaCl UNITS PER unit cell are 4. `therefore` Number of TETRAHEDRAL voids `= 2 xx 4 = 8` Number of octahedral voids = 4 .
