Actinides

Actinides are a series of 15 chemical elements in the periodic table, ranging from atomic number 89 (actinium) to 103 (lawrencium). They are known for their radioactive properties and include elements like uranium and plutonium, which are crucial in nuclear energy and weapons. Typically found in nature only in trace amounts, actinides are mostly synthetic and have various uses in industry, medicine, and research. Their unique characteristics, such as the ability to release large amounts of energy, make them both valuable and hazardous, requiring careful handling and safety measures.
