Fluorine

Fluorine is a highly reactive, pale yellow gas at room temperature, belonging to the halogen group in the periodic table. It has the strongest attraction for electrons among elements, making it very reactive and capable of forming compounds with most other elements. Fluorine is used in the production of refrigerants, toothpaste (fluoride), and in manufacturing certain plastics. Because of its reactivity, it can be dangerous to handle, requiring specialized equipment and safety measures. Despite its hazards, fluorine plays a critical role in various industrial and medical applications, leveraging its unique chemical properties.
