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? Hint: The answer is 0.228nm, but you must still show all your work with clear...
