Concept explainers
Interpretation:
Radioactive nuclide is a term that is used to designate an atom with what type of nucleus has to be chosen from the given options.
Concept Introduction:
If the reaction occurs in the nucleus of an atom then it is known as nuclear reaction. These reactions are not considered as ordinary
Unstable nuclei emits radiation to become stable. The process of this radiation emission is known as radioactivity.

- Radioactivity is a phenomenon of the spontaneous emission of: A. protons (alpha particles) B. electrons (beta particles) C. gamma rays (short wave electromagnetic waves) D. All of the abovearrow_forwardRefer to the following figure (first three rows of the periodic table) to answer the questions below. What element does not react with other elements?

- Many radioactive isotopes are used in medicine for imaging and treatment purposes. The specific isotopes used depends on the particular organ or body system being studied (for example, Xe-133 is used to image lung function and blood flow.) Technetium-99m is a common radioactive isotope using for a variety of medical applications. It is produced from the decay of Molybdenum-99 and has a half-life of 6.01 hours. What are some of the applications of Tc-99m? While harder to access, another radioactive isotope of technetium, Tc-93, has a half-life of 2.73 hours. If it were easier to harvest, would this be a good substitute for Tc-99m? (remember to explain why for full credit) While Tc-99m has a half-life of 6.01 hours, its decay product has a half-life of 213,000 years. While the medical community considers it to be reasonably safe, within the limits of testing, does this make sense considering both chemical and biological principles? What are possible ways that you might deal with or…arrow_forward8) Which of the following is NOT a use for isotopes discussed in class? a. Diagnosing Cancer b. Killing Cancer cells c. Explosive demolition d.Tracking environmental changearrow_forwardCarbon-14 is a radioactive material. It contains 6 protons and 8 neutrons. During the process of Carbon-14 decay, one of its 8 neutrons becomes a proton and an electron is formed in the process. Based on this information, select all that apply. The mass number is unchanged by the decay of Carbon-14. The mass number is changed by the decay of Carbon-14. After decay the atom is still Carbon. After decay the atom is not Carbon.arrow_forward
