Chlorite Ion
The compound Mo(ClO2)3 is named molybdenum(III) chlorite. In this formula, molybdenum has a +3 oxidation state, and each chlorite ion (ClO2-) has a -1 charge, resulting in three chlorite ions balancing the charge of one molybdenum ion.
The hydrogen Ion H+, however this reacts with the water to form hydronium is the aqueous cation H3O+
In barium chlorite, Ba(ClO2)2, the oxidation state of barium (Ba) is +2. Each chlorite ion (ClO2-) has a charge of -1. Within the chlorite ion, the oxidation state of oxygen is -2, so for two oxygen atoms, that totals -4. To balance this, the oxidation state of chlorine must be +3. Therefore, the oxidation state of Cl in Ba(ClO2)2 is +3.
By charge, I assume you mean oxidation number. Oxygen's oxidation number is a very dependable -2, with only a few strange exceptions. A better question would be "What is chlorine's oxidation number in ClO4-?" The answer would be +7.

Chlorite Ion
It isn't actually the 'molecular' formula because it is not molecule you ask about, but here is the formula of the chlorite anion:ClO2- in which the oxidation state of Cl is +3 and of O it is -2 (as ever in oxy-compounds). (The acid of this base is HCLO2, name: hydrogen chlorite, or better known as chlorous acid.)
The symbol for the chlorite ion is ClO2-.
Chloride: Cl- Chlorite: ClO2- Chlorate: ClO3-
The chlorite ion is a negatively charged polyatomic ion with the formula ClO2-. It contains one chlorine atom and two oxygen atoms. Chlorite ions are commonly found in disinfectants and bleaching agents.
HClO is an acid, in aqueous state, involving a polyatomic ion. You MUST recognize the polyatomic ion in the formula. There is no other way to figure out the name. If you don't recognize the polyatomic, then you're sunk without a trace. The polyatomic ion is ClO¯ and its name is hypochlorite. Any time you see the "ite" suffix, you change it to "ous" and add the word acid. The name of HClO is hypochlorous acid.
ClO2^- is chlorite anion Do not confuse with ClO3^- is chlorate anion Cl^- is chloride anion.
The compound Mo(ClO2)3 is named molybdenum(III) chlorite. In this formula, molybdenum has a +3 oxidation state, and each chlorite ion (ClO2-) has a -1 charge, resulting in three chlorite ions balancing the charge of one molybdenum ion.
Chlorine Dioxide.It is a covalently bonded atom, therefor it uses prefixes.I believe the question is referring to an ion, therefore the correct name is the chlorite ion.
The chemical formula for chlorite ion is ClO2- and the other oxy-anions of chlorine are (IUPAC names in parentheses); ClO- : Hypochlorite ion [ Chlorate(I) ion ] ClO3- : Chlorate ion [ Chlorate(V) ion ] ClO4- : Perchlorate ion [ Chlorate(VII) ion ]
The nitrate ion is NO3- and the minus sign superscripted means it has a -1 charge. The chlorite ion is ClO2- and the minus sign superscripted means it, too, has a -1 charge.
