Solid State Question 299
Question: A solid is made of two elements X and Z. The atoms Z are in ccp arrangement while the atoms X occupy all the tetrahedral sites. What is the formula of the compound-
Options:
A) XZ
B) $ XZ_2 $
C) $ X_2Z $
D) $ X_2Z{ _3} $
Show Answer
Answer:
Correct Answer: C
Solution:
[c] Let the number of Z atoms in the ccp arrangement = 100 Thus the number of tetrahedral sites = 200 Since all the tetrahedral sites are occupied by X atoms, the number of X atoms = 200 Hence ratio of $ X:Z=2:1 $ Thus the formula is $ X_2Z $
