Which of the following halogens is liquid at room temperature?
Answer Details
The halogen that is liquid at room temperature is Bromine.
Bromine is a reddish-brown liquid with a boiling point of 58.8°C, which is lower than room temperature (typically around 20-25°C). This means that bromine is in its liquid state at room temperature.
In contrast, fluorine and chlorine are gases at room temperature, while iodine is a solid. Bromine is the only halogen that is a liquid at room temperature.
