Mn2O3 =
Mn 3+
O 2-
and
MnBr2 =
Mn2+
Br1-
Therefore,
The first binary compound (Mn2O3) contains the ion Mn3+
Manganese (III) oxide, Mn2O3, contains the Mn3+ ion.
Mn2O3
Mn2P2
An ionic compound, as it contains a metal ion "Mg2+" and a non metal ion "Br-".
If the compound contains a polyatomic ion, simply name the ion.
PbCO
The total numbers of positive and negative parts of the compound must be the same. Manganese (IV) has 4 positive charges per ion and phosphate has 3 negative charges per ion; therefore the formula is Mn3(PO4)4.
