Magnesium Bromide Formula: Magnesium (Mg) is an elemental substance classified within Group 2 (IIa) of the Periodic Table, specifically among the alkaline earth metals. It boasts an atomic number of 12 and stands as the lightest structural metal. Compounds containing magnesium find extensive utility in both construction and medical fields. Furthermore, magnesium is an essential component within the cellular structure of all living organisms.
Bromine, conversely, is an element belonging to Group 17 (Group VIIA) and is characterized by an atomic number of 35. Designated by the chemical symbol "Br," bromine exists as a toxic crimson-hued liquid, classifying it as a halogen element.
Magnesium bromide, the product of combining bromine and magnesium, is represented by the chemical formula MgBr2. It is obtainable in two distinct forms: the anhydrous variety, presenting as white hygroscopic crystals, and the hexahydrate form, which manifests as colorless monoclinic crystals.
