Question

if a face centered cubic lattice atom A occupies the corner positions and atom B occupies the face center position.if one atom B is missing from one of rhe face centered points the formula of the compound​

Answer 1

In a face centred cubic lattice atom A occupies the corner position and atom B occupies the face centre position. If one atom of B is missing from one of the face centred point the formula of compound is

A)

As the molecule is having FCC structure,

∴ let the formula of the compound be Ax

A)

As the molecule is having FCC structure,

∴ let the formula of the compound be AxBy

No of atom of A=18×8=1

Number of atom of B = 6×12−12=52

As one atom is missing and where the contribution of each atom in FCC is 12

Thus the formula is A1B52 or A2B5
