Actinides

Subject: Chemistry

Book: General Chemistry

The actinides (atomic numbers 89–103) include radioactive elements like uranium and plutonium. They are characterized by filling 5f orbitals and often exhibit multiple oxidation states. Many actinides are synthetically produced in nuclear reactors. Uranium (U) is used for nuclear power generation, while plutonium (Pu) is a key component in nuclear weapons. Their radioactive nature demands careful handling and storage. Actinide chemistry is vital for energy and defense sectors.
