silver dumps a face centered cubic unit cell structure illustrate how the number of atoms per unit cell for that silver atoms are obtained. Alright so remember we have eight corners to our cube, So each one is 1/8 of an atom and we have eight corners involved. So 18 top times eight equals one adam. Also remember that on each face we have half of a sphere and there are six faces faces to acute. That's time six. So that's gonna give us three atoms when we add them together. That explains why a face centered cubic unit cell is four atoms per one unit itself. So this is our atoms to unit cell ratio. It's a 4-1 ratio.
