MnO Mn2+ and O2- = Mn2O2 but you'd simplify and it becomes MnO
Mn - Manganese(IV) has a 4+ charge CN - Cyanide has a 1- charge therefore... Mn(CN)4
The formula for manganese(VII) arsenide is Mn3As7.

Permanganic compounds contain manganese in a +7 oxidation state. Since oxygen in oxides always has a -2 oxidation state, the formula for permanganic oxide is Mn2O7.
Mn - Manganese(IV) has a 4+ charge CN - Cyanide has a 1- charge therefore... Mn(CN)4
MnO- 4
== == == == The chemical symbol for manganese is Mn The Atomic number is 25 The Average atomic mass is 54.938 045
Fluoride ions have a charge of -1, so three fluoride ions have a total charge of -3. Since there is only one manganese ion in the formula, the manganese ion has to have a charge of +3, so that the overall charge is 0.
The formula for manganese carbonate is MnCO3.
The formula for manganese(VII) arsenide is Mn3As7.
