Which of the following halogens is liquid at room temperature?
Answer Details
Bromine is the halogen that is liquid at room temperature. This is because it has the lowest boiling point of all the halogens, meaning it can easily evaporate to become a gas at higher temperatures.
At room temperature, which is typically around 20-25 degrees Celsius (68-77 degrees Fahrenheit), bromine remains in its liquid state because its boiling point is 59 degrees Celsius (138 degrees Fahrenheit). Chlorine and fluorine are gases at room temperature because they have much lower boiling points than bromine. Iodine is a solid at room temperature, as it has a higher boiling point than bromine and therefore requires higher temperatures to turn into a liquid.
