1.	the number of tetrahedral voids per unit cell in NaCl crystal is ………… .A. 4B. 8C. twice the number of octahedral voidsD. four times the number of octahedral voids
Answer» Correct Answer - B,C NaCl has fcc arrangment of `Cl^(-)` ions. Thus, Number of `Cl^(-)` ions in pakcing per unit cell=4 Number of tetrahedral voids `=2xx` No. of particles present in close packing `=2xx4=8`
