Fluorine is a highly reactive and corrosive element that is a pale yellow gas at room temperature. It is the most electronegative element, making it extremely reactive and capable of forming compounds with almost all other elements. Fluorine is commonly used in toothpaste and water fluoridation to prevent tooth decay.
