To determine the number of 'nearest' and 'next nearest' neighbors that sodium has in a face-centered cubic (FCC) lattice, we can follow these steps: ### Step 1: Understand the FCC Lattice Structure In a face-centered cubic (FCC) lattice, atoms are located at each of the corners of the cube and at the centers of each face of the cube. ### Step 2: Identify Nearest Neighbors The nearest neighbors of an atom in an FCC lattice are the atoms that are closest to it. For an atom located at a corner of the FCC unit cell, the nearest neighbors are the atoms located at the centers of the adjacent faces. ...
