Q1(i). The half-life of 20kg of Bismuth-210 is 20 minutes. Explain this statement. (ii). A radioactive species has 128 atoms present. If it has half-life of 5years, calculate the number of atoms remaining after 20years of decay. (iii). Eight alpha particles and six beta particles are emitted from an atom of U of atomic number 92 and mass number 238 before it achieve stability. Determine the nucleon number of the final product in the chain reaction.
