Periodic Table Elements 82-92

Periodic Table Elements 82-92

• Lead (Pb): Heavy metal known for its density and malleability, used in batteries and radiation shielding.
• Bismuth (Bi): Brittle metal with low toxicity, often used in cosmetics and pharmaceuticals as a substitute for lead.
• Polonium (Po): Rare and highly radioactive element, discovered by Marie Curie, used in nuclear applications and as a heat source in space equipment.
• Astatine (At): Halogen with limited availability, highly radioactive, and exhibits properties similar to iodine; used in targeted alpha-particle cancer therapy.
• Radon (Rn): Colorless, odorless gas, a product of radium decay, recognized for its health risks as a radioactive gas found in homes.
• Francium (Fr): Extremely rare and highly radioactive alkali metal, known for its short half-life and instability; little is known about its chemical properties due to its scarcity.
• Radium (Ra): Radioactive alkaline earth metal, historically used in luminous paints, but currently recognized for its health risks and environmental impacts.
• Actinium (Ac): Silvery-white radioactive metal; serves as an initiator in nuclear reactors and in radiation therapy for cancer treatment.
• Thorium (Th): Radioactive element with potential as a safer nuclear fuel; is abundant and produces less long-lived radioactive waste compared to uranium.
• Protactinium (Pa): Rare, highly radioactive element, used in some forms of advanced nuclear reactors due to its ability to absorb neutrons.
• Uranium (U): Naturally occurring radioactive element used primarily as fuel for nuclear reactors and in the production of nuclear weapons, known for its isotopes U-235 and U-238.
