$XY$

Vedclass · Answer

(A) The $ccp$ lattice is formed by the element $Y$. The number of octahedral voids generated is equal to the number of atoms of $Y$ present in the lattice. Since all the octahedral voids are occupied by the atoms of $X$,the number of atoms of $X$ is equal to the number of atoms of $Y$. Thus,the ratio of atoms of $X$ to $Y$ is $1:1$. Therefore,the formula of the compound is $XY$.

$A$ compound is formed by two elements $X$ and $Y$. Atoms of the element $Y$ (as anions) make $ccp$ and those of the element $X$ (as cations) occupy all the octahedral voids. What is the formula of the compound?
