Can anyone define what a super anoxide ion is>

Also can you define radioactive decay?
thanks

I won't even pretend to understand what you are talking about but I thought while you waited for an answer for someone who is an expert in this field you might find this information usefull:
Radioactive decay

My answer is not matching up 100% with your question. From Masterton and Slowinski. Chemical Principles they describe the Preoxide as OO-- {2 oxygens with negative 2 charge}
The superoxide Ion would be OO- 2 oxygens - 1 charge. Then negative charge makes it an anion
I'm not familiar with the term 'anoxide'.

A reaction K(s)+O2(g)--> K02(s) potassium superoxide.

good luck ppe
