A) 6, 6
B) 8, 4
C) 4, 4
D) 4, 8
Correct Answer: B
Solution :
The \[C{{a}^{2+}}\] ions are arranged in (ccp) arrangement, i.e. \[C{{a}^{2+}}\] ions are present at all corners and tat the center of each face of the cube. the fluoride ions occupy all the tetrahedral sites. This is 8 : 4 arrangement i.e., each \[C{{a}^{2+}}\] ion is surrounded by \[8{{F}^{-}}\] ions and each \[{{F}^{-}}\] ion by four \[C{{a}^{2+}}\] ions.You need to login to perform this action.
