####27. A compound formed by elements $X$ and $Y$ crystallizes in a cubic structure in which the $X$ atoms are at the corners of a cube and the $Y$ atoms are at the face-centres. The formula of the compound is

[2004]

(a) $X Y_{3}$

(b) $X_{3} Y$

(d) $X Y_{2}$

Show Answer

Solution:

(a) For the given cubic structure,

No. of $X$ atoms at the corners $= 8 \times \frac{1}{8} = 1$

No. of $Y$ atoms at the face-centres $= 6 \times \frac{1}{2} = 3$

$∴$ Formula of the compound $= X Y_{3}$
