Fe3+ is smaller. Its ionic radius is 63 pm, while Fe2+ has an ionic radius of 77 pm. (For comparison, the Fe atom has a radius of 140 pm.) This is because the outermost electron in the 2+ ion is pulled off to form the 3+ ion. This outermost electron was the most weakly held. The remaining electrons are closer to the nucleus.

Which is most likely to be reduced Fe2 Cu2 Fe3 or Zn2?
Answer this question… Fe3+
Is an oxidation half-reaction A. Fe2 plus Fe3 plus plus e- B. Fe3 plus plus e- Fe2 plus C. Fe(s) Fe(l) D. Fe plus 2e- Fe2 plus?
A. Fe^2+ ==> Fe^3+ + e- is an oxidation reactionB. Fe^3+ +e- ==> Fe^2+ is a reduction reactionC. Fe(s) ==> Fe(l) is neither an oxidation nor a reduction reaction. It is a phase change.D. Fe + 2e- ==> Fe^2+ is not a possible reaction.
