Lewis structure
Draw the Lewis structure of rhombic sulfur. Start by drawing the overall structure of the molecule: Count the total valence electrons of the sulfur (n_S, val = 6) atoms: 8 n_S, val = 48 Calculate the number of electrons needed to completely fill the valence shells for sulfur (n_S, full = 8): 8 n_S, full = 64 Subtracting these two numbers shows that 64 - 48 = 16 bonding electrons are needed. Each bond has two electrons, so the above diagram has all the necessary bonds. There are 8 bonds and hence 16 bonding electrons in the diagram. Lastly, fill in the remaining unbonded electrons on each atom. In total, there remain 48 - 16 = 32 electrons left to draw: Answer: | |
