. For more help, watch this general tutorial on drawing Lewis Structures for compounds like the Sulfate ion. Both sulfur and oxygen have 6 valence electrons. I also go over hybridization, shape and bond angles. In lewis structure of sulfate ion, there should be charges on several atoms due to -2 charge. Let's do the SO4 2- Lewisstructure, for the sulfate ion. Let's do the SO4 2- Lewis structure, for the sulfate ion. SO42-. Lewis structure of sulfate ion is drawn in this tutorial step by step. Watch the video and see if you missed any steps or information. . For more help, watch this general tutorial on drawing Lewis Structures for compounds like the Sulfate ion.
