The atomic mass number of copper is 64. Assume that atoms insolid copper form a cubic crystal lattice. To visualize this,imagine stacking tiny sugar cubes into a big cube. If you pretendthere is a copper atom in the middle of each sugar cube, thendissolve the sugar away, the copper forms a cubic lattice. What isthe smallest distance between copper atoms?
Hint: The answer is 0.228nm, but you must still show all yourwork with clear understanding!
