Formula: AsI3
I think you mean As2Ba3. That would be Barium Arsenide.
FeAs2 is the most common arsenide (míneral lollingite) it is not ionic. There are arsenide phases FeAs and Fe3As2 corresponding to iron(III) arsenide and iron (II) arsenide, again the bonding is not ionic.
Copper arsenide = Cu3As
The formula for Iron(II) sulfate is FeSO4.
The chemical formula for sodium arsenide is Na3As.
Iron (III) Arsenide
I think you mean As2Ba3. That would be Barium Arsenide.
Copper (III) doesn't exist; copper(II) arsenide is Cu3As2.
FeAs2 is the most common arsenide (míneral lollingite) it is not ionic. There are arsenide phases FeAs and Fe3As2 corresponding to iron(III) arsenide and iron (II) arsenide, again the bonding is not ionic.
The chemical formula for iron(II) hydride is FeH2.
The chemical formula for cuprous arsenide is Cu3As.
Copper arsenide = Cu3As
Formula of 3 types of Iron oxides: Iron(II) oxide= FeO Iron(III) oxide= Fe2O3 Iron(II,III) oxide= Fe3O4
The formula for iron(II) bromide is FeBr2.
The formula for Iron(II) Fluoride is FeF2.
The formula for Iron(II) sulfate is FeSO4.
An arsenopyrite is a silvery-grey ore of arsenic - a mixed arsenide and sulphide of iron, chemical formula FeAsS.
