Question

what is are lattice point in fcc structure

Answer 1

face centered cubic lattice contains 4 lattice point per unit cell. The maximum packing density occurs when the atoms have a radius which equals one quarter of the diagonal of one face of the unit cell.

Answer 2

Answer:

The face-centered cubic system (cF) has lattice points on the faces of the cube, that each gives exactly one half contribution, in addition to the corner lattice points, giving a total of 4 lattice points per unit cell (​1⁄8 × 8 from the corners plus ​1⁄2 × 6 from the faces

4 lattice points

Watch as atoms divide to give a total of 2 lattice points in the Body Centred Cubic (BCC) unit cell and 4 lattice points in the Face Centred Cubic (FCC) unit cell

Explanation:

The face centered cubic lattice contains 4 lattice point per unit cell. The maximum packing density occurs when the atoms have a radius which equals one quarter of the diagonal of one face of the unit cell.

Cubic: 3

Hexagonal: 1

Tetragonal: 2

Orthorhombic: 4
