Used example, \(\ce{CaBr2}\) contains one bronze element (calcium, ampere group 2 [or 2A] metal) and a nonmetallic element (bromine, a group 17 [or 7A] nonmetal). That, it is mostly probably an ionic compound (in fact, it is ionic).
Calcium bromide is the name for compounds with the chemical formula CaBr2(H2O)x. Individual compounds include the anhydrous material (x = 0), the hexahydrate (x = 6), and the rare dihydrate (x = 2). All are white powders that dissolve in water, and from these solutions crystallizes the hexahydrate. The hydrated form is mainly used in some drilling fluids.
