What state of matter is chlorine?

Explanation:
At room temperature, chlorine is a gas because its boiling point is far below typical room temperatures. Chlorine boils at about -34°C, and its melting point is around -101°C, so in everyday conditions (roughly 20–25°C) it exists as a gaseous diatomic molecule (Cl2). Only if you cool it well below -34°C would it condense into a liquid, and further cooling below -101°C would make it solid. Plasma would require ionization, which doesn’t happen under normal conditions.
