They lack only one electron to form a complete shell or subshell, and are extremely active chemically. Chemical activity increases as you move upward in the group, fluorine being the most active element in the Periodic Table. At room temperature, fluorine and chlorine are gases, bromine is liquid, and iodine is solid.They form diatomic molecules in the pure state. The halogens are poisonous, and chlorine gas and chlorine compounds have been used as chemical weapons.hey lack only one electron to form a complete shell or subshell, and are extremely active chemically.

Answer by Nicole Morgan. Confidence votes 65. The element bromine is in the state of a liquid at room temperature (room temperature is roughly 20 degrees Celsius). This is because it's boiling point is 59 degrees Celsius, which is 39 degrees more then room temperature. Actually, Bromine is a Liquid at room temperature it never changes to a gas at room temperature when it is heated up to 300 or so...Kelvin. 1 person found this useful.
