Question

Expalin them face cubic unit cell?​

Answer 1

Answer:

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).

Answer 2

Answer:-

face-centered cubic: There are also atoms or ions in the center of each of the six faces of the unit cell. simple cubic: The atoms or ions are at the corners of the unit cell only. unit cell: The smallest portion of a crystal lattice that shows the three-dimensional pattern of the entire crystal.
