Which reasonably attainable chemical best attracts electrons? Answered
I'm building a secret project, but I need a chemical that can attract electrons. It has to be easily attainable, relatively cheap, and it can't easily hurt me. I think that my question, is (if possible), which safe chemical is the best at attracting electrons? If one wouldn't have a noticeable effect under those parameters, is there one that would be noticeable at all?
