The oxidation number for gold (Au) in gold(III) arsenide (AuAs3) is +3. This is because arsenic (As) typically has an oxidation number of -3, and since the compound is neutral, the total oxidation numbers must balance out to zero.
The oxidation number of a Cobalt (III) ion is +3. This means that the Cobalt atom has lost three electrons.
The oxidation number of aluminum (Al) in Al2S3 is +3, while the oxidation number of sulfur (S) is -2. Each aluminum atom has an oxidation number of +3, and each sulfur atom has an oxidation number of -2 in order to balance the charge in the compound.
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.
The oxidation number of chlorine in iron III hypochlorite is -1. This is because the overall charge of the hypochlorite ion (ClO-) is -1, and in iron III hypochlorite, the iron atom has a +3 charge.

This is iron II, III oxide and features iron in both the 2+ and 3+ oxidation states.
'Oxidation number' and oxidation state are often used interchangeably. Oxidation state is a formal way of determining the degree of oxidation of an atom or ion or molecule; for ions the oxidation number is equal to the ionic charge. In non ionic compounds the most electronegative element is assumed to "own" the electrons. So in say InP which is a semiconductor and not ionic, the oxidation state of indium is +III and P is -III. Oxidation number is a convention used in complexes. Ligands are removed from the ion with all bonding electrons. Often the oxidation number and oxidation state have the same values but calculating the the oxidation number of N in ammonia, H is removed as hydride ion, H- you get the strange looking result of nitrogen with an oxidation number of +3. In contrast the oxidation states of N and H would be calculated as -III and +1

The oxidation number of Fe in Fe2O3 (iron (III) oxide) is +3. This is because oxygen usually has an oxidation number of -2, and since there are three oxygen atoms in Fe2O3, the total oxidation number contributed by oxygen is -6. This means the Fe atoms must have a combined oxidation number of +6 to balance the charge, leading to an oxidation number of +3 for each Fe atom.
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.
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.
