In the Body Centered Cubic Cell (BCC) there is an additional atom in the center of the cube, and in the face centered cubic cell, an atom is shared between two unit cells along the face. Please watch the YouTube video as this can help a lot.

16 Ιαν 2023 · Face-centered Cubic Unit Cells. Face-centered Cubic (FCC) unit cells indicate where the lattice points are at both corners and on each face of the cell. This is a more common type of unit cell since the atoms are more tightly packed than that of a Simple Cubic unit cell.
24 Νοε 2022 · The Face-Centered Cubic (FCC) unit cell can be imagined as a cube with an atom on each corner, and an atom on each face. It is one of the most common structures for metals. FCC has 4 atoms per unit cell, lattice constant a = 2R√2, Coordination Number CN = 12, and Atomic Packing Factor APF = 74%.
A face-centered cubic solid has atoms at the corners and, as the name implies, at the centers of the faces of its unit cells. Atoms in an FCC arrangement are packed as closely together as possible, with atoms occupying 74% of the volume. This structure is also called cubic closest packing (CCP).
23 Αυγ 2021 · The packing atoms (Na +) are in a face centered cubic arrangement. The octahedral holes in a face-centered cubic lattice can be found at the edges and in the center of the unit cell, and they are filled by the chloride ions.
20 Μαΐ 2024 · Face-Centered Cubic (FCC) Unit Cell. In a face-centered cubic unit cell, one lattice point is at each corner of the cube, similar to the simple cubic unit cell, and an additional lattice point is at the center of each face of the cube. The FCC structure is commonly found in metals such as copper and aluminum.
Unit Cells of Metals. The structure of a crystalline solid, whether a metal or not, is best described by considering its simplest repeating unit, which is referred to as its unit cell. The unit cell consists of lattice points that represent the locations of atoms or ions.
