# Half-life of a radioactive element is the time required for the element to reduce to half of its initial concentration. The rate of change of concentration is calculated by the formula A(t)=Ao(12)tγA(t)=Ao(12)tγw here γγ is the half-life of the material, AoAo is the initial concentration of the radioactive element in the given sample, A(t)A(t) is the concentration of the radioactive element in the sample after time tt. If Radium has a half-life of 1600 years and the initial concentration of Radium in a sample was 100%, then calculate the percentage of Radium in that sample after 2000 years.
