Is sodium face centered?
Sodium has a face-centered cubic unit cell. The density of sodium is 1.53g/cm3.
What type of unit cell does sodium pack as?
Many metals pack in cubic unit cells. The density of a metal and length of the unit cell can be used to determine the type for packing. For example, sodium has a density of 0.968 g/cm3 and a unit cell side length a of 4.29 Å.

Which unit cell is a face-centered cubic unit cell?
| Cubic Cell Name | Atoms per Unit Cell | Coordination Number |
|---|---|---|
| simple cubic (sc) | 1 | 6 |
| face-centered cubic | 4 | 12 |

Is sodium a BCC?
The body-centred cubic (bcc) structure is the most stable form for sodium metal at 298 K (25°C).
What is face centered cubic unit cell?
A face-centered cubic unit cell structure consists of atoms arranged in a cube where each corner of the cube has a fraction of an atom with six additional full atoms positioned at the center of each cube face. As such, each corner atom represents one-eighth of an atom.
