<p><a href="page.php?w=Bravais_lattice">lattice vector</a>. Such a model is sensible because crystal <a href="page.php?w=Ion">ions</a> that form the lattice structure are typically on the order of tens of thousands of times more massive than electrons,making it safe to replace them with a fixed potential structure, and the macroscopic dimensions of a crystal are typically far greater than a single lattice spacing, making edge effects negligible. A consequence of this potential energy function is that it is possible to shift the initial position</p><p>
