Fluorine: Properties, Structure and Uses

Abstract

Fluorine is a highly reactive non-metal and the lightest member of the halogen group. It is the most electronegative element in the periodic table, which explains its strong ability to form compounds with almost all other elements. Fluorine is a pale yellow gas at room temperature and does not occur freely in nature. It is found only in stable compounds due to its extreme reactivity. Despite dangerous properties, fluorine and its compounds are widely used in everyday life, including toothpaste, medicine, and medical imaging. Its unique physical and chemical characteristics make fluorine an important element in both science and modern technology.
