What is the balanced nuclear equation for the positron emission of bromine-75?

Identify which is false from the following statements about nuclear weapons and nuclear power plants.

The radioactivity of the spent fuel from a fission reactor is substantially higher than that of the initial fuel. What types of decay would you anticipate to be predominant among the fission products given that only two or three neutrons are generated per fission event and knowing that the nucleus undergoing fission has a neutron-to-proton ratio typical of a heavy nucleus?

What is the preferred mode of decay for nuclei that are neutron-rich? for nuclei that are neutron-poor?

Identify whether the following nuclide is stable or radioactive: Platinum-196, Francium-224, ⁶⁴₂₉Cu, ⁶⁰₂₈Ni, ⁹⁸₄₃Tc. Explain.

What type of radioactive decay process will ⁶⁹₃₀Zn, a radionuclide, most likely undergo?

Even though the elements in the lanthanide series have comparable chemical reactivity, their abundances in the crust of the Earth differ by two orders of magnitude. The graph below displays the relationship between relative abundance and atomic number. Which statement explains why elements with even atomic numbers have more abundant isotopes? 

The creation of Livermorium involved the collision of a target ²⁴⁸₉₆Cm with accelerated ions of an isotope which we will denote as Z. After the collision, the product atom immediately releases neutrons and Livermorium is formed. 

²⁴⁸₉₆Cm + Z → ²⁹⁶₁₁₆Lv → ²⁹³₁₁₆Lv + 3 ¹₀n

Isotope Z is remarkable in that it is very long-lived despite having an unfavorable neutron-to-proton ratio (its half-life is on the scale of 10¹⁹ years). Can you offer an explanation for its unusual stability?

The band of stability curves upward at higher atomic numbers, why?

A radioactive isotope emits alpha-radiation with an activity of 11.2 mCi and each particle having an energy of 8.49×10^–13 J. Assume a person weighing 65.5 kg is exposed to this radiation for 20.0 seconds and that 25.0% of the emitted alpha has been absorbed. Calculate the dose absorbed by the person in millirads and grays.
