Answer:
Copper monobromide.
Step-by-step explanation:
To name the compound, we shall determine the oxidation number of copper in CuBr. This can be obtained as follow:
Br = –1
Cu =?
CuBr = 0
Cu + (–1) = 0
Cu – 1 = 0
Collect like terms
Cu = 0 + 1
Cu = +1
Thus, oxidation number of copper in CuBr is +1.
Therefore, the name of the compound is copper (I) bromide or copper monobromide
