Question
In a CCP lattice of X and Y, X atoms are present at the corners while Y atoms are at face centers.Then the formula of the compound would be if one of the X atoms from a corner is replaced by Z atoms (also monovalent)?
Options
A.X7Y24Z2
B.X7Y24Z
C.X24Y7Z
D.XY24Z
Solution
X = 7 × 
; Y = 
× 6 = 3. ; z = 
⇒ X7/8 Y3 Z1/8 = X7 Y24 Z
; Y = × 6 = 3. ; z = ⇒ X7/8 Y3 Z1/8 = X7 Y24 ZCreate a free account to view solution
