Lewis structure
![Draw the Lewis structure of trisulfur. Start by drawing the overall structure of the molecule, ignoring potential double and triple bonds: Count the total valence electrons of the sulfur (n_S, val = 6) atoms: 3 n_S, val = 18 Calculate the number of electrons needed to completely fill the valence shells for sulfur (n_S, full = 8): 3 n_S, full = 24 Subtracting these two numbers shows that 24 - 18 = 6 bonding electrons are needed. Each bond has two electrons, so in addition to the 2 bonds already present in the diagram we expect to add 1 bond. To minimize formal charge sulfur wants 2 bonds. Identify the atoms that want additional bonds and the number of electrons remaining on each atom: Fill in the 2 bonds by pairing electrons between adjacent highlighted atoms, noting that the valence shell of the central atom has been expanded: Answer: | |](../image_source/b9172e4ac2d0618687d268ba9e2f110a.png)
