Properties of the Most Reactive Nonmetal

The most reactive nonmetal, fluorine, is a pale yellow gas at room temperature. It is the lightest halogen and the most electronegative element, meaning it has a strong tendency to attract electrons. This high electronegativity is a key factor in its extreme reactivity. Fluorine has the following notable properties:

Atomic Number: 9
Atomic Mass: Approximately 19 u
Electron Configuration: [He] 2s²2p⁵
Electronegativity: 3.98 (Pauling scale)
Melting Point: -219.67°C (-363.41°F)
Boiling Point: -188.11°C (-306.60°F)

Fluorine's high electronegativity and small atomic size make it highly reactive. It readily forms compounds with almost all other elements, including noble gases like xenon and krypton, which are typically inert. This reactivity is due to fluorine's strong tendency to gain an electron to achieve a stable electron configuration.
