Transcript: Hi, this is Dr. B. Let's do the SO4 2- Lewis structure, for the sulfate ion. On the periodic table: Sulfur, 6 valence electrons; Oxygen also has 6, we have 4 Oxygens, multiply by 4; and these 2 valence electrons up here, we need to add those, as well. That gives us a total of 32 valence electrons.
