Question

A compound is formed by two elements x and y atoms of the elements y as anion make ccp and those element x as cation occupy all octahedral voids formula of compound is

Answer 1

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

• ⭐.. 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 ${XY}$.
