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.

Balard discovered the element in 1826. One of the very cool physical properties of bromine is that it is the only nonmetallic element that is a liquid at room temperature. Don't let that cool trait overwhelm you. Bromine is a very dangerous chemical, purified or in gas form.Bromine is a member of the halogen family of elements.hen you think of bromine, think reddish-brown.
