+3 for gold
-3 for arsenic
The chemical formula for gold(III) arsenide is AuAs. It is composed of one gold atom (Au) and one arsenic atom (As) in a 1:1 ratio.
The chemical formula for gold (III) arsenide is AuAs. In this compound, gold is in the +3 oxidation state, denoted by the Roman numeral III in parentheses. Arsenic is in the -3 oxidation state, so one gold atom combines with one arsenic atom to form a stable compound with a 1:1 ratio.
0 in elemental form +3 in most of its stable compounds
The oxidation number of a Cobalt (III) ion is +3. This means that the Cobalt atom has lost three electrons.
I think you mean As2Ba3. That would be Barium Arsenide.

Iron (III) Arsenide
Copper (III) doesn't exist; copper(II) arsenide is Cu3As2.
The oxidation number of a Cobalt (III) ion is +3. This means that the Cobalt atom has lost three electrons.
Metallic aluminium has the oxidation number zero. In compounds in the form of ions, it takes the oxidation number +III.Metallic aluminium has the oxidation number zero. In compounds in the form of ions, it takes the oxidation number +III.
The oxidation state of iron in iron (III) compounds is +3. This means that each iron atom in these compounds has lost 3 electrons.
I think you mean As2Ba3. That would be Barium Arsenide.
Iron(iii) ion = +3
The oxidation number of phosphorus in chromium(III) phosphate is +5. In chromium(III) phosphate, each chromium ion has a +3 oxidation state, and the overall compound is electrically neutral, so the oxidation number of phosphorus must be +5 to balance the charges.
An example is the ferric ion: Fe(III) or Fe3+.
