MO and  MBr₂

Explanation:

The compounds that would be formed are MO and MBr₂:

 Here is a simple approach to find them molecular formula of the compounds.

Every atom has combining power which illustrates the number of electrons usually lost, gained or shared by atoms of elements during chemical combinations.

    Species:

        M            2 valence electrons  to be lost

        O             2 valence electrons needed

        Br             1 valence electron needed

                                  M                               O

combining
