हिन्दीA compound is formed by two elements A and B. The element B forms cubic close packed structure and atoms of A occupy \( 1/3 \) of tetrahedral voids. If the formula of the compound is \( \text{A}_x\text{B}_y \), then the value of \( x + y \) is in option
Correct answer · Option 1
5
Explanation
Let B = 4, Tetrahedral voids = 8. A = \( \frac{1}{3} \times 8 = \frac{8}{3} \). Formula = \( \text{A}_{8/3}\text{B}_4 = \text{A}_2\text{B}_3 \). Thus \( x=2, y=3 \), \( x+y = 5 \).
