In each case, one site is larger than the other, and is normally occupied by impurity atoms. For FCC, this larger one is located at the center of each edge of the unit cell; it is WebInterstitial Solid Solutions. When the atomic radius of the element is sufficiently small, this element can occupy interstitial sites in the structure of \ce {A}. Only atoms of small diameter can lead to solid solutions of this type, for example \ce {C}, \ce {N}, \ce {O}, \ce {H}, \ce {B}. Let r_s be the radius of the atoms in the original lattice.
