Magnesium bromide is a chemical compound of magnesium and bromine, with the chemical formula MgBr2. It is white and deliquescent crystalline solid. It is often used as a mild sedative and as an anticonvulsant for treatment of nervous disorders. It is water-soluble and somewhat soluble in alcohol. It can be found naturally in small amounts in some minerals such as: bischofite and carnallite, and in sea water, such as that of the Dead Sea. WebMar 16, 2024 · Hence, the chemical formula for magnesium bromide is M g B r 2. Note: When any atom is present in the form of anion, as it gains electrons, then its name is changed to ‘ide’ in the end. Therefore, bromine changes to bromide here. The valence of any element can be identified from its electronic configuration, as Mg has 2 valence electrons ...
