"WebClose-packing in 2-D 1. When a number of rows are stacked up, a two-dimensional crystal plane is generated. There are two ways of stacking the rows. 2. One way is for the rows to lie one above the other, with one sphere exactly above another.Here the spheres are aligned horizontally as well as vertically. 3. " - Close-packed stacking
