The half life period of a certain radioactive element with disintegration constant 0.0693 per day is 1.4 days 14 days 10 days 140 days 2. Nuclide X has a half-life of 1 day and nuclide Y has a half-life of 5 days. In a particular sample, the activities of X and Y are found to be equal. When the activity is tested again after 10 days, the activity will be Mostly due to nuclide X Due equally to nuclides X and Y Entirely due to nuclide X Mostly due to nuclide Y 3. Isotopes provide evidence for the existence of Nuclei Electrons Neutrons Protons 4. "The amount of energy released when a nucleus is assembled from its component nucleons" What is being defined above? binding effect nucleon mass energy 5. "Device that allows the nuclear reactions to occur in a place that is sealed from the rest of the environment" Write down what is being defined container heat exchanger mass storage unit 6. In a fission chain reaction, neutrons from one fission reaction cause further fission reactions. Energy from one fission reaction causes further fission reactions nuclei produced in one fission reaction cause further fission reactions. Gamma radiation produced in one fission reaction causes further fission reactions 7. A nucleus decays by the emission of an electron. What are the mass (nucleon) number and the atomic (proton) number of the resulting nucleus? Mass number Proton number A. 89 38 B. 90 39 C. 91 38 D. 91 39 A C B D 8.
