β-SulfurIn the structure to the left the atom sizes are more realistic, taking into account the overlap of one atom's orbitals with another to form a covalent bond. However, even though it is more realistic, you can see that it is a less useful way to depict the structure.
We can describe the lattice structure more completely by considering repeating units. These are described on the next page.
