Effective number of atoms in a face centered cubic (FCC) unit cell is equal to ________
Effective number of atoms in a face centered cubic (FCC) unit cell is equal to ________ Correct Answer 4
In an FCC unit cell, there are eight atoms: one at each corner of the cube and six face centered atoms of the six planes of the cube. As corner atoms are shared by eight adjacent cubes and the face centered atoms by two adjacent unit cells, total effective number of atoms in an FCC unit cell will be 4.
