Predict the state of fluorine at room temperature?

• A. Gas
• B. Liquid
• C. Solid
• D. Plasma

Answer: (A)

Fluorine stays as a gas at room temperature because its molecules are very small and held together by only weak forces. The boiling point of fluorine is around -188°C, far below typical room temperatures, so the molecules have enough energy to escape into the gas phase and remain there. In other words, the intermolecular forces between F2 molecules are too weak to condense into a liquid or solid at everyday conditions. This is also why heavier halogens have higher boiling points and can be liquids or solids at room temperature, while fluorine remains a gas. Plasma would require ionization, which doesn’t occur for fluorine under normal room-temperature conditions.
