Can someone explain why oxygen is more electronegative than chlorine in the perchlorate ion? I am also still confused on how to determine which Lewis structure is most plausible based on the oxidation number. I understand that chlorine has an oxidation number of +7, but I'm not sure where to go from there in terms of relating this to the formal charges we see in each of the structures provided.

Hey! From my understanding, Oxygen is more electronegative than Chlorine in the perchlorate ion because Oxygen has a slightly higher electronegativity than Chlorine when going based the Pauling Electronegativity Scale. Oxygen would also have a partial negative charge and Chlorine has a partial positive charge.

I believe oxygen has a slightly higher electronegativity because it is closer to the top right corner. the electronegativity gradually increases from the bottom left corner to the top right. you can see the values by looking at the pauling electronegativity chart.
