Question

Atomos neutros de um certo elemento representativo M apresentam dois elétrons em sua camada de valência. As fórmulas corretas para seu óxido normal e brometo são, respectivamente: (Dados: O = 6A e Br = 7A) a) M20 e MBr. B) MO2 e MBr2. C) MO e MBr2. D) M2O2 e M2Br.

Answer 1

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

powers                       2                                2

Exchange

of power                     2                                2

   Formula of compound         MO

                                   M                           Br

combining

powers                       2                            1

Exchange

of power                    1                             2  

                                               MBr₂
