Brief description |
| |
* Bromine is the only liquid nonmetallic element.
* It is a heavy, mobile, reddish-brown liquid, volatilizing readily at room temperature to a red vapor with a strong disagreeable odor, resembling chlorine, and having a very irritating effect on the eyes and throat
* It is readily soluble in water or carbon disulfide, forming a red solution, is less active than chlorine but more so than iodine
* It unites readily with many elements and has a bleaching action; when spilled on the skin it produces painful sores.
