Atoms in Face-Centered Cubic Cells Face of the Cube

The video tutorial explains the structure of a face centered cubic unit cell, detailing the arrangement of atoms. It describes how six face centered atoms are shared between unit cells, contributing half an atom each, resulting in three face centered atoms per unit cell. Additionally, it covers the eight corner atoms, each contributing one-eighth, totaling one corner atom. The tutorial concludes that a face centered cubic unit cell contains four atoms in total.
