A metallic element crystallises into a lattice having a ABC ABC …… pattern and packing of spheres leaves out voids in the lattice. What type of structure is formed by this arrrangement ?

All real structures are three dimensional structures. They can be obtained by stacking two dimensional layers one above the other while placing the second square dose packed layer above the first we follow the same rule that was followed when one row was placed adjacent to the other. The second layer is placed over the first layer such that the spheres of the upper layer are exactly above there of the first layer. In his arrangement spheres of both the layers are perfectly aligned horizontally as well as vertically.
