What are some properties and some pros and cons of using plutonium?

Plutonium is a radioactive, silvery-gray metal with the atomic number 94. It has a high density and a relatively low melting point, making it useful in nuclear applications. Pros of using plutonium include its ability to generate significant amounts of energy through nuclear fission and its use in advanced nuclear reactors and weapons. However, its cons include long-lived radioactivity, potential environmental hazards, and proliferation risks associated with its use in nuclear weapons.
