Name one metal ion that's not multivalent.
Please use another screen name. Damon is the name used by one of our regular Jiskha tutors.
Nevertheless perhaps Hydrogen is correct :)
No, hydrogen is not correct but you get 50% for thinking of it; i.e., that's a close answer. Actually, H has a valence of +1 in most compounds but in hydrides it is -1 (as in LiH or NaH or CaH2).
I would pick any element in group I.
Thank you both very much for your assistance
