The solid-state structure of silicon is shown below.

(a) Describe this crystal as pc, bcc, or fcc.
(b) What type of holes are occupied in the lattice?
(c) How many Si atoms are there per unit cell?
(d) Calculate the density of silicon in g/cm³ (given that the cube edge has a length of 543.1 pm).
(e) Estimate the radius of the silicon atom.
