A sample of polonium-210 has an initial mass of 3200 milligrams (mg). If the half-life of polonium-210 is 14 days, how many mg of the sample remains after 70 days? PLS HELP I WILL MARK BRAINLIEST TO THE FIRST ANSWER

Particle exchange energy though elastic collision , hope this .

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.

Answer/// he concludes that the atom particles can be broken due to the paddle wheel being moved by particles coming out of the metal;
