Question
The total number of atoms contained in the FCC unit cell is: square 4 The FCC structure is based o square ct with square . atoms. Hence the FCC structure has a coordination and can be represented in three layers of atoms in an square arrangement. In the FCC latti hexagonal packing number of square The FCC structure is highly efficient in packing atoms, with a packing efficiency of around square This high packing efficiency gives metals with FCC structures, like aluminium , copper, and gold, their characteristic density and stability FCC metals tend to be ductile because of the high number of slip planes, making them more malleable and less brittle.

The total number of atoms contained in the FCC unit cell is 4. The FCC structure is based on the cubic crystal system with a coordination number of 12. It can be represented in three layers of atoms in a face-centered arrangement. In the FCC lattice, the atoms are arranged in a hexagonal packing. The FCC structure is highly efficient in packing atoms, with a packing efficiency of around 74%. This high packing efficiency gives metals with FCC structures, like aluminum, copper, and gold, their characteristic density and stability. FCC metals tend to be ductile because of the high number of slip planes, making them more malleable and less brittle.
