Question

A compound is formed by 2 elements x and y atoms of elemnts x as anions make ccp and those of element y

Answer 1

The ccp lattice is formed by the element Y. The number of octahedral voids generated would be equal to the no of atoms of Y present in it. Since all the octahedral voids are occupied by the atoms of X, the number would also be equal to that of the element Y. Therefore the formula of the compound is XY.

Answer 2

${\huge{\underline{\underline{\mathcal{\red{♡ANSWER♡}}}}}}$

• ⭐.. The ${ccp}$ lattice is formed by the element ${Y}$.
• ⭐.. The number of octahedral voids generated would be equal to the number of atoms of ${Y}$ presebt in it.
• ⭐..Since all the octahedral voids are occupied by the atoms of ${X}$ their number would also be equal to that of the element ${Y}$.
• ⭐... Thus, the atoms of elements${X}$and${Y}$ are present in equal number or 1:1 ratio, Therefore the formula of compound is ${XY}$.
