The side of the unit cell is of length 2 r, where r is the radius of the atom. Face-centered cubic [ edit] FCC structure For a face-centered cubic unit cell, the number of atoms is four.
WebThe number of atoms per unit cell in a simple cubic, face-centered cubic and body-centred cubic are 1,4,2 respectively. (1) The number of atoms contained in one simple cubic unit cell of monoatomic substance is 1. 8 atoms are present at 8 corners of a simple cubic unit cell. Each atom contributes one eigth to the unit cell. WebJul 7, 2024 · Crystal Structure. The crystal structure of a diamond is a face-centered cubic or FCC lattice. Each carbon atom joins four other carbon atoms in regular tetrahedrons (triangular prisms). Based on the cubic form and its highly symmetrical arrangement of atoms, diamond crystals can develop into several different shapes, known as 'crystal habits'.
