1. A U-238 atom (uranium-238) has a nucleus with 92 protons and an atomic mass of 238.0507882 u. What is the nuclear binding energy per nucleon in this atom? 2. When Dr. Bruce Banner becomes angry and undergoes a transformation into the Incredible Hulk, his blood plasma becomes saturated with Na-24 atoms. These radioactive sodium atoms decay into stable Mg-24 by beta decay, along with the release of two high-energy gamma rays, to which Dr. Banner is immune. After initially...
1.Describe what happens to a carbon-11 atom when it undergoes positron emission. The decay of a carbon-11 atom _____(options;changes a nuetron into proton, changes proton into neutron, is hit with a neutron, reconfigures its protons and neutrons) and this causes it to emit______(options; a negatively charged electron sized particle, a positively charged electron sized partticle, two atoms and several neutrons, two neutrons and two protons) 2.An atom undergoes radioactive decay according to this equation: ___. What is the identity of...
The illustration shows one possible way that a nucleus of uranium-235 (235U) can undergo neutron-induced fission. (a) Rank the following objects in order of their binding energy per nucleon, from largest to smallest. If any two objects have the same binding energy per nucleon, state this. Explain how you made your ranking. (i) The uranium-235 (235U) nucleus (ii) The tellurium-134 (134Te) nucleus (iii) The zirconium-99 (99Zr) nucleus (iv) The three neutrons Activity 27-4 [continued]. (b) Using your results from part...
Activity 27-4. Nuclear fission (Accompanies Section 27-4] 1 A uranium nucleus (235U) absorbs a neutron. The result is a uranium nucleus (236U) in an excited state. 3 The excited uranium nucleus fissions into two smaller, more tightly bound nuclei... ...as well as a few neutrons. These can trigger the fission of other 235U nuclei. 3 neutrons Neutron + 2350 236U 134 Te 9976 Z = 0 protons Z = 92 protons N = 1 neutron N = 143 neutrons A=Z+N...
A Uranium-235 atom undergoes fission in the following net reaction (induced fission involves an intermediate step as U-236 which we will ignore): U-235 --> X + Y + 2n U-235 is the 'parent', X and Y are 'daughters' (= fission products), n = free neutron. 1 u = atomic mass unit = 1.66 x 10-27 kg mn = mass of a neutron = 1.008665 u mp = mass of a proton = 1.007825 u 1 eV = 1.602 x 10-19...

Breaking radiation E. None of the above 14. What is "chain reaction" of nuclear reactions? A. the joining together of protons and neutrons to form atomic nuclei continuously B. the joining together of light nuclei to form heavy ones continuously C. the successive fissions of heavy nuclei induced by neutrons...
41. A patient receives 3.0 mL of a solution containing technetium-99m for a breast image. If the activity of the technetium-99m is 9.5 mCi/mL, what is the dose received by the patient? A) 3.2 mCi B) 29 mCi C) 320 μCi D) 9.5 mCi E) 28.5 mCi 42. When an atom of uranium-235 is bombarded with neutrons, it splits into smaller nuclei and produces a great amount of energy. This nuclear process is called A) fission B) fusion C) decomposition...
thank u so much! 6. One form of nuclear radiation, beta decay, occurs when a neutron changes into a proton, an electron, and a neutral particle called an antineutrino: n → pt + e + De, where ve is the symbol for an antineutrino. When this change happens to a neutron within the nucleus of an atom, the proton remains behind in the nucleus while the electron and neutrino are ejected from the nucleus. The ejected electron is called a...
