What does the roman number III indicate in cobalt III oxide indicate?
The roman number III indicates that the ion of cobalt present in this form of cobalt in the cobalt oxide is Co3+. Since cobalt also exists as a Co2+ form, these must be distinguished in some way. The standard is to use roman numerals to denote the charge. Both Cobalt (III) oxide and Cobalt (II) oxide still have the chemical formula of Co3O4.
Which element has an oxidation number plus 3?
An example is the ferric ion: Fe(III) or Fe3+.
What is the name of Co2 SO3 3?
Cobalt(II) carbonate
What is the oxidation number of an atom of gold III?
0 in elemental form +3 in most of its stable compounds
What is the oxidation number charge of the ion?
The oxidation number is a measure of the charge an atom would have if all its bonds were 100% ionic. It can be positive, negative or zero.
What is the oxidation number of ironIII?
Iron(iii) ion = +3
What is difference between cobaltic chloride and cobaltous chloride?
Cobaltous ion has a +2 oxidation state. Cobaltic ion has a +3 oxidation state Cobaltous chloride: CoCl2 Cobaltic chloride: CoCl3

What oxidation number?
'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
