You are graphing the atomic radius (size of an atom) for the specified elements.   This is a line graph that, but not your typical line graph.  
You will have a set of lines using regular pencil (for the Periods) and another set of lines using colored pencils (for the Groups).

Hairy thick gross thing? idk

Your awser would be a acetone

Ithink iit might be

Answerthe half-reaction having the greatest tendency to occur at the anode:     i₂(aq) + 2e⁻  ⇄ 2i⁻  ;   e = +0.53 v======oxidation occurs at the anode. we must therefore find the half-reaction with the greatest tendency to oxidize.the given values of e are reduction potentials (the form of the half-reactions are of reduction).the lower the reduction potential, the higher the potential to oxidize. the half-cell with the lowest reduction potential will have the greatest tendency to oxidize at the anode.the half-reaction having the greatest tendency must be    i₂(aq) + 2e⁻  ⇄ 2i⁻    e = +0.53 vbecause its reduction potential is the lowest out of the three.
