Answer:

Chromium(II) bromide = #CrBr_2#.

Explanation:

For chromium(II) bromide it is stipulated that the metal centre is in a #II^+# oxidation state. Since we deal with #Cr^(2+)#, and the normal oxidation state of the halogens is #-I#, i.e. #X^-#, if they are combined we naturally get the give formula.
