Br⁻
Bromide
Br⁻ is the symbol for the bromide ion. It is an anion that has one extra electron compared to neutral bromine, Br. Bromide is a halogen, which is a non-metal element in Group 17 of the periodic table.
Bromide ions are commonly found in salts such as potassium bromide (KBr) and sodium bromide (NaBr). These salts are often used in photographic film and paper, as well as in certain medications such as sedatives and anticonvulsants.
In terms of its chemical properties, the bromide ion has a larger atomic radius compared to the chloride and fluoride ions due to its added electron. This results in greater polarizability and weaker ionic bonds with other ions forming the salt.
Overall, bromide ions have important industrial and medical applications, and their chemical behavior plays a crucial role in these fields.
