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.

What is the rule when writing the name of an ionic compound that contains a transition metal?
If the transition metal has more than one ion, you write the charge as a Roman numeral. For example copper can have an ion with a charge of 1+ and an ion with a charge of 2+. If they were combined with oxygen, they would be named copper (I) oxide and copper (II) oxide respectively.
What do Roman numerals after an ion name indicate?
It is only needed after transition metals, so it should say how many valence electrons are in the transition metal. Ex: If iron has 3 valence electrons and it is combined with oxygen, it would be written as Iron (III) oxide. I hope It helped!
What are Iron III oxide oxidation numbers?
You have answered the question for yourself.!!!!! Iron (III) Oxide [ Fe2O3] has the oxidation number of '3'. Written in Roman Numerals ' III ' . An atom of iron has 6 electrons in its outer most energy (valence) shell. Of these six electrons only '3' are involved in combining with another atoms. This other '3' remain uncombined. Similarly Iron (II) Oxide NB Iron as all the other Transition [ 'd' block ] elements, exhibits variable oxidation numbers. NNB When you read Roman Numerals in a chemical name formula, it indicates the oxidation state. NNNB Archaically Iron(II) oxide is Ferrous Oxide , and Iron(III) oxide is Ferric oxide. NNNNB Potassium permanganate has the manganese in oxidation state '7', written as Potassium manganate(VII) [ KMnO4] .
Why is fo2o3 named iron oxide?
First of all to correct your formula. It is ' Fe2O3'. Note the use of Capital Letters and the position of the numbers. Secondly ' Fe' is the Latin initials for the word 'iron', which is 'Ferrum'. Hence Fe2O3 is Iron Oxide. Iron exhibits different oxidation states. For given compound of iron, it is correctly named as 'Iron (III) Oxide '. ' Said as 'Iron three oxide '. In everyday terms , this is 'RUST'. Or mined as 'iron ore'. Archaically it would be named as 'Ferric Oxide'. Note the root word 'ferric/ferrum' for iron. Also note the use of Roman Numerals (III) for '3' , to indicate oxidation state. Iron also exhibits different oxidation states. This makes for the other iron compound ' FeO ' , which is Iron (II) Oxide, and is archaically named as Ferrous Oxide. It is in oxidation state (II) '2'. This is much less common and is green in colour.
What is co hso4 3?
Cobaltic Bisulfate The formula is poorly constructed. It should probably appear as Co(HSO4)3. "Cobaltic" is somewhat archaic. The Stock system, using Roman numerals, is preferred. Therefore, it would be called cobalt (III) bisulfate or cobalt (III) hydrogen sulfate.
What is the letter u in roman numerals?
roman numerals indicate a number not a letter as such there is no answer to that question
In the name cobalt 11 phosphate what does the roman numeral reveal about cobalt?
The valence of cobalt, in this case 2; Cobalt (II) phosphate.
CuO in roman Numerals?
CuO is Copper (II) oxide in roman numerals.
What is the point of Roman numerals in science?
Roman numerals are a simple way to distinguish between closely-related objects. Two examples:In chemistry, Roman numerals can indicate the valence number of an element in similar compounds, such as with iron (II) oxide and iron (III) oxide.In astronomy, they can enumerate planets, such as Sol III (Earth) and Sol IV (Mars).
What is the rule when writing the name of an ionic compound that contains a transition metal?
If the transition metal has more than one ion, you write the charge as a Roman numeral. For example copper can have an ion with a charge of 1+ and an ion with a charge of 2+. If they were combined with oxygen, they would be named copper (I) oxide and copper (II) oxide respectively.
Why is the compound FeO not named iron oxide?
The compound FeO is actually named iron(II) oxide. This is because the iron in FeO is in the +2 oxidation state, so it is referred to as iron(II) to indicate the charge of the ion. The Roman numeral is used to specify the oxidation state of the metal ion in the compound.
What do Roman numerals after an ion name indicate?
It is only needed after transition metals, so it should say how many valence electrons are in the transition metal. Ex: If iron has 3 valence electrons and it is combined with oxygen, it would be written as Iron (III) oxide. I hope It helped!
Do you add Roman numerals to indicate the oxidation state?
Yes, Roman numerals are used to indicate the oxidation state of an element in a compound, particularly for transition metals that can have multiple oxidation states. For example, in iron(III) oxide, the Roman numeral III signifies that iron has an oxidation state of +3. This notation helps clarify the specific charge of the metal in the compound, ensuring accurate communication in chemical formulas.
What does a Roman numeral represent for the oxidation number?
In chemistry, Roman numerals indicate the oxidation state of an element in a compound, particularly for transition metals and some main group elements. For example, in iron(III) oxide (Fe₂O₃), the Roman numeral III signifies that iron has an oxidation state of +3. This notation helps to clarify the specific charge of the metal ion in compounds where it can exhibit multiple oxidation states.
How can roman numeral in a chemical name be used to write a chemical formula?
The Roman numeral following the cation tells you the oxidation number of that cation. For example, Cu(ll)chloride tags you it is CuCl2 because the (ll) after Cu indicates an ox. no. of 2+.
What is 2003 in Roman Numerals?
In Roman Numerals, the number 1,000 is represented by "M", thus, to indicate 2,000 you would double it. 1 is represented by "I". So 2003 would be MMIII in Roman Numerals.
What is the name of the compound MnO2?
MnO2 is Manganese (IV) Oxide. It is also known as manganese dioxide, manganese oxide or as the naturally occurring mineral pyrolusite. Please see the related links below.
