This arrangement is called a face-centered cubic (FCC) solid. A FCC unit cell contains four atoms: one-eighth of an atom at each of the eight corners (8×18=1 8 × 1 8 = 1 atom from the corners) and one-half of an atom on each of the six faces (6×12=3 6 × 1 2 = 3 atoms from the faces).
What is the formula of FCC?
The APF of an FCC structure is equal to the volume of the atoms in the unit cell divided by the volume of the unit cell. To further break this down, we can express “a” in term of “r”. Cancelling common terms, we get APFFCC = 0.74. In other words, 74% of the volume of the unit cell is occupied by atoms.
How do you calculate R FCC?
The relation between edge length (a) and radius of atom (r) for FCC lattice is √(2a) = 4r .
