The atomic mass number of copper is 64. Assume that atoms in
solid copper form a cubic crystal lattice. To visualize this,
imagine stacking tiny sugar cubes into a big cube. If you pretend
there is a copper atom in the middle of each sugar cube, then
dissolve the sugar away, the copper forms a cubic lattice. What is
the smallest distance between copper atoms?
