â¦The answer is Bromine because the question clearly states, at room temperature this halogen is a liquid, and on any periodic table, bromine is a different colour to the other elements showing that it is a liquid or it melts close to room temperature.
solid at 22 C. liquid at 22 C. gas at 22 C. liquid at 30 C. In the periodic table above, black squares indicate elements which are solids at room temperature (about 22 C)*, those in blue squares are liquids at room temperature, and those in red squares are gases at room temperature.
