The metal polonium (which was named by Marie Curie after her homeland, Poland) crystallizes in a primitive cubic structure, with an atom at each corner of a cubic unit cell. The atomic radius of polonium is 167 pm. Sketch the unit cell and determine (a) the number of atoms per unit cell (b) the coordination number of an atom of polonium (c) the length of the side of the unit cell. 

I studied him his somber black coat, the tilt of his head, the concentration in his eyes. Meanwhile, the water in the bain-marie hissed, another carriage set off outside, and faintly, from a distant corner, I thought I heard my father s cough. Now I knew why I had been led through the labyrinth of the miscarried embryo, the bleak homecoming, the dead babies, the furnace shed—it was all to show me this.
