Bromine is an elemental chemical with symbol Br and automatic number 35. It is the third lightest halogen and is fuming red-brown liquid at room temperature that evaporates readily to a colored gas. It has the properties of chlorine and iodine.

It is nonmetal in group 17 of the periodic table. Bromine has the electron configuration {Ar} 3d ten 4s two 4p five, with the seven electrons in the fourth and outermost shell acting as it’s valence electrons. Like all halogens, it is one electron short of a full octet. Corresponding to periodic trends, it is intermediate in electronegativity between chlorine and iodine.
