Referencing the periodic table, determine the number of neutrons and protons in each of the following Isotopes: a) Li-7 b) C-14, c) Fe-58 , d) Hg-201, and e) Pu-239. Explain your answers.

Which of the following statements is/are incorrect? Select all that apply. You may choose more than one, one, or none of the options. For certain elements, their isotopes are highly unstable.. For certain elements, the atomic mass is now reported as an atomic mass interval rather than as a single specific value. The isotopic abundances of certain elements vary from sdurce to source. For elements with more than one isotope, the atomic mass is the sum of the isotopic masses. It is not possible to make precise measurements of isotopic masses.

Nuclear decay can be useful.  Generally, the radiation interacts with other matter in a specific way.  Consider the following item: (a) a PET scanner  For the above example, provide: the correct symbol (with atomic number and mass number) of the element used. A balanced equation that describes the decay that takes place. How the radiation interacts with matter in a way that provides a benefit.
