Read the passage about nuclear energy.
"A chain reaction takes place when a single fission reaction triggers multiple additional fission reactions. If there is a sufficient quantity of a radioactive element present under appropriate conditions, an ongoing chain reaction ensues. This phenomenon is referred to as a self-sustaining chain reaction. Each fission reaction generates a significant amount of heat, which can be harnessed for electricity production. The process of electricity generation closely resembles that of a steam-electric power plant. However, in the case of a nuclear power plant, it is the heat generated by fission that causes water to boil. This boiling water produces steam, which, in turn, drives turbines to generate electricity. In contrast, conventional steam-electric plants rely on the heat produced by burning coal, oil, or gas to achieve the same water boiling process."

The option that characterizes an atomic attribute that renders certain atoms suitable for applications in nuclear medicine and nuclear power generation is:
"Isotopes of an element vary in the quantity of neutrons they possess. Certain unstable isotopes are utilized in the fields of nuclear medicine and nuclear power generation."
To arrive at this answer, we need to understand the concept of isotopes, stability, and their applications in nuclear medicine and power generation.
Isotopes are different forms of the same chemical element that have the same number of protons but varying numbers of neutrons in their nucleus. This variation in neutron count leads to different isotopes with different masses.
Certain isotopes are unstable, meaning they have an excess of energy that they need to release to become more stable. These unstable isotopes are called radioisotopes. They typically undergo radioactive decay, where they emit radiation to achieve a more stable state.
In the fields of nuclear medicine and nuclear power generation, certain unstable isotopes are utilized. In nuclear medicine, radioisotopes are used for diagnostic imaging (such as positron emission tomography or PET scans) and cancer treatments (through targeted radiation therapy). In nuclear power generation, some radioisotopes are used as fuel in nuclear reactors to produce heat and generate electricity.
Therefore, the correct option is: "Isotopes of an element vary in the quantity of neutrons they possess. Certain unstable isotopes are utilized in the fields of nuclear medicine and nuclear power generation."
