Bromine is a chemical element; it has symbol Br and atomic number 35. It is a volatile red-brown liquid at room temperature that evaporates readily to form a ...
Bromine is intermediate in reactivity between chlorine and iodine, and is one of the most reactive elements. Bond energies to bromine tend to be lower than those to chlorine but higher than those to iodine, and bromine is a weaker oxidising agent than chlorine but a stronger one than iodine.
The high-bromine brines in the Appalachian Basin are found in Silurian and Devonian rocks, in Pennsylvania, Ohio, and West Virginia. The principal source of the brine in Ohio and West Virginia was the Pottsville Formation, also called the Big Salt Sand. In Pennsylvania, bromine brine was pumped from the Pocono Sandstone. [2]
A bromide ion is the negatively charged form (Br −) of the element bromine, a member of the halogens group on the periodic table.Most bromides are colorless. Bromides have many practical roles, being found in anticonvulsants, flame-retardant materials, and cell stains. [3]
Bromine (35 Br) has two stable isotopes, 79 Br and 81 Br, and 35 known radioisotopes, the most stable of which is 77 Br, with a half-life of 57.036 hours.. Like the radioactive isotopes of iodine, radioisotopes of bromine, collectively radiobromine, can be used to label biomolecules for nuclear medicine; for example, the positron emitters 75 Br and 76 Br can be used for positron emission ...
Bromism is the syndrome which results from the long-term consumption of bromine, usually through bromine-based sedatives such as potassium bromide and lithium bromide. Bromism was once a very common disorder, being responsible for 5 to 10% of psychiatric hospital admissions, but is now uncommon since bromide was withdrawn from clinical use in ...
Bromine dioxide (BrO 2) Bromine can form several different oxides: Dibromine monoxide (Br 2 O) Bromine dioxide (BrO 2) Dibromine trioxide (Br 2 O 3) Dibromine pentoxide (Br 2 O 5) Tribromine octoxide (Br 3 O 8) Also, a number of ions are bromine oxides: Hypobromite (BrO −) Bromite (BrO 2 −) Bromate (BrO 3 −) Perbromate (BrO 4 −) And the ...
Anthropogenic and natural sources of bromine. The major sources include sea spray, salt lakes, marshes, volcanos, anthropogenic sources. Sinks include exchange of brominated compounds with the stratospheric and troposphere.Bromine's chemistry is linked to other halogens such as chlorine and iodine amplify atmospheric cycling that contributes to troposphere and stratosphere ozone layer ...
