Which of the following is a radioactive metal used for generating nuclear power?

• A. Cobalt
• B. Gold
• C. Uranium
• D. Plutonium

Answer: (C)

Uranium is a radioactive metal widely utilized in generating nuclear power. This element has qualities that make it suitable for use in nuclear reactors, where nuclear fission can occur. During the fission process, the nucleus of a uranium atom splits into smaller parts, releasing a significant amount of energy, which is harnessed to produce electricity.

Uranium is naturally occurring and is mined in various parts of the world. Its isotopes, particularly Uranium-235, are pivotal in sustaining a controlled chain reaction necessary for energy production in nuclear reactor systems. Its capacity to release energy from relatively small amounts of material also contributes to its importance as a significant energy resource in the push for sustainable energy solutions.

Other elements listed, while they may have various applications, do not possess the same critical attributes for nuclear energy generation. Cobalt and gold, for example, are not used for this purpose as they lack the necessary nuclear properties to facilitate a sustained fission reaction required in a nuclear power context. Plutonium, while also a radioactive metal used in some nuclear power applications, is less common for initial fuel loads as compared to uranium, which is the primary fuel used worldwide in nuclear reactors.
