Question

Example 7 :<br />A solid is made of two elements X and Y. Atoms X are in fcc arrangement and Y atoms occupy<br />all the octahedral sites and alternate tetrahedral sites. What is the formula of compound?<br />Solution :<br />Na 8<br />v<br />Atoms of X forming fcc lattice means they occupy 8 corners and 6 face centres hence number<br />of atoms = 4<br />Tetrahedral sites = 8<br />Number of Y atoms = 4<br />Octahedral sites = 4<br />Number of Y atoms = 4<br />.:. Total number of Y atoms = 8<br />X:Y<br />4:8 or 1: 2. Hence formula of compound is XY2​
