Chemistry - Solid State Question with Solution | TestHub

Aluminium has an FCC structure, so it does not form a simple cubic lattice (A is false). In FCC, each atom has 12 nearest neighbors, confirming statement C. The coordination number of FCC is 12, and the unit cell is face-centered (B is true). The second nearest neighbors in FCC are 6, but their distance is a=404a = 404a=404 pm, not 202 pm, so D is false.
