Century Dictionary and Cyclopedia
- n. Chemical symbol, Br; atomic weight, 80. A non-metallic element allied in its chemical relations to chlorine and iodine. It is a dark-reddish liquid, opaque except in thin layers, sparingly soluble in water, having a specific gravity of 3.19 at 32° F. It is volatile, and emits at ordinary temperatures reddish vapors which have a powerful suffocating odor, and are intensely irritating to the mucous membrane. When dropped on the skin, bromine produces corrosive sores. It is not found native, but occurs combined with bases in very minute quantities in sea-water and the ashes of marine plants, and in larger amount in certain mineral springs. Some ores of silver also contain bromine in combination. With hydrogen bromine forms hydrobromic acid (HBr), and with bromine or hydrobromic acid most metals form compounds called bromides, which are extensively used in medicine. Bromine itself is also used medicinally in very dilute solutions. Also called
- n. uncountable A nonmetallic chemical element (symbol Br) with an atomic number of 35; one of the halogens
- n. countable A bromine atom in a molecule

- n. (Chem.) One of the halogen elements, related in its chemical qualities to chlorine and iodine. Atomic weight 79.8. Symbol Br. It is a deep reddish brown liquid of a very disagreeable odor, emitting a brownish vapor at the ordinary temperature. In combination it is found in minute quantities in sea water, and in many saline springs. It occurs also in the mineral bromyrite.
- n. a nonmetallic heavy volatile corrosive dark brown liquid element belonging to the halogens; found in sea water

“I have found it to yield more satisfactory results than bromine, which is much more expensive.”
“-- Of all common photographic paper, the best, because the least troublesome in making, and the most satisfactory in result, is that which is termed bromine paper, and which is thus prepared: -- Dissolve one hundred grains of bromide of potassium in one ounce of distilled water, and soak the paper in this solution.”

“We use a kind of bromine tablet in our spa in the US and it works great.”
“For example, by biosynthetic methods it is easy to introduce a heavy atom such as bromine into the molecule; the heavy atom can be placed unambiguously in three dimensions by the calculated Patterson distribution; the remaining atomic positions appear with no difficulty at all in the following three-dimensional electron-density distribution and, on refinement, the atoms appear beautifully clearly.”
