A compound is formed by two elements X and Y. Atoms of the element Y ( – InterviewSolution

1.	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 ?
Answer» Solution :Let number of Y atoms = n. Total number of octahedral voids = n SINCE X occupies all the octahedral voids, the FORMULA of the compound is `X_nY_n` . Taking `n = 1 implies XY` is the formula of compound.
