Well, we start with an oxygen molecule, #O_2#.......

Explanation:

Now dioxygen, #O=O#, has 16 electrons. How do we know this? For oxygen, #Z=8#, and thus neutral #O_2# necessarily has #"16 electrons"#. And thus #"superoxide"# MUST have #"17 electrons...."#

I'd try to represent this as a Lewis structure, but not on this editor. Try to do this yourself on paper as an exercise.
