Magnetite, a magnetic oxide of iron used on recording tapes, crystallises with iron atoms occupying 1 8 of the tetrahedral - Chemistry - The Solid State

Question

Magnetite, a magnetic oxide of iron used on recording tapes,
crystallises
with iron atoms occupying
1
8 of the tetrahedral holes and
1
2 of the
octahedral holes in a closed packed array of oxides ions What
si the
formula of magnetite?

Vinod Sharma · Answer

let atoms in ccp be 1
Fe=1/8*2+1/2*1=3/4, O=1
Formula of the compound= Fe in subscript 3/4 O in subscript
1
=Fe3O4
