1) When Uranium-235 (atomic number 92/mass number 235) is struck by a slow neutron it is split into two smaller elements and 3 neutrons (atomic number 0/mass number 1). If one of the elements it splits into is Strontium (Sr) (atomic number 38/mass number 90), what is the other element it splits into? Must include atomic number and mass number. 2) Uranium-238 eventually decays into Lead-206. The half-life of Uranium-238 is 4.5 x 109 or 4.5 billion years. A rock...
