How many atoms are in fcc
WebThe arrangement of atoms in face centered cubic unit is as shown in figure. An FCC unit cell consists of eight corner atoms and each and every corner atoms is shared by eight adjacent unit cell. Therefore, each and every corner atom contributes 1/8 of its part to one unit cell. The total number of atoms by corner atom = 1/8 x 8 = 1 atom.
