A crystalline solid consists of atoms stacked up in a repeating lattice structure. Consider a crystal as shown in figure p1. The atoms reside at the corners of the cubes of side L = 0.200 nm. One piece of evidence for the regular arrangement of atoms comes from the flat surfaces along which a crystal separates, or cleaves, when it is broken. Suppose this crystal cleaves along a face diagonal as in p2. Calculate the spacing d between two adjacent atomic planes that separate when the crystal cleaves.
