Calcium has six naturally occurring isotopes : Calcium 40, Calcium 42, Calcium 43, Calcium 44 , Calcium 46, and Calcium 48. Based on Calcium's reported atomic mass (40.078) , which do you think is the most abundant in nature ? Please Explain why

The closer the atoms are to becoming ionic the more highly dense the negatively charged side gets.

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.
