Problem VII.A


In the case of C, where the lattice constant (a) was measured to be 14.17 Å,

  1. Calculate the distance between nearest neighbors.
    Answer: 10.02 Å.

  2. Given that the radius of C0 is approximately 3.53 Å, calculate the distance between spheres.
    Answer: ~2.96 Å.

    Note: This compares to a distance of 3.35 Å between the planar sheets of carbon atoms in graphite.
