In 2003 an international team of scientists at the Lawrence Berkeley Laboratories claimed to have synthesized a new element by smashing a krypton-86 nucleus into a lead-208 target.If a neutron was released from the collision,what was the resulting nuclide?

Question

Quizplus · Accepted Answer

When a neutron is released from the collision, the resulting nuclide would have an atomic number one less than krypton-86, which is 36. Therefore, the resulting nuclide would have an atomic number of 35, which is represented by the symbol Br (bromine). The resulting nuclide would also have a mass number of 208 + 1 = 209, which is represented by the number in subscript after Br. The only choice that fits this description is choice B.
