So you know the charge of the cation. For example, because Iron isn't in group 1 (charge 1+) or group 2 (charge 2+), its charge is undetermined until you give it one with roman numerals.
Iron (I) Carbonate - Fe2CO3
Iron (II) Carbonate - FeCO3
Iron (III) Carbonate - Fe2(CO3)3
Iron (IV) Carbonate - Fe(CO3)2
Although the above compounds are made using the same elements, the roman numerals make them different.

What must be use when writing the chemical name for a compound with a transition metal?
Many transition metals can have multiple different oxidation numbers. When writing out the chemical name, you need to specify the oxidation number with a roman numeral.For example, Copper (II) oxide would be this: CuOWhile Copper (I) oxide would be this: CuO2
When is the oxidation state of metal indicated in the name of a comoound?
The oxidation state of a metal is indicated in the name of a compound when the metal can exhibit more than one oxidation state. This is commonly seen in transition metals and some post-transition metals, where Roman numerals are used to specify the oxidation state. For example, in iron(III) chloride (FeCl₃), the Roman numeral III indicates that iron has an oxidation state of +3. In contrast, if a metal has only one oxidation state, it is not typically specified in the compound's name.
What is the compound name for Aui3?
The compound name for AuI3 is gold(III) iodide. In this compound, gold has an oxidation state of +3, which is indicated by the Roman numeral III in the name. It consists of one gold atom and three iodide ions.
What is the compound name for Fe (CN)3?
The compound name for Fe(CN)₃ is iron(III) cyanide. In this compound, iron has a +3 oxidation state, which is indicated by the Roman numeral III in the name. The cyanide ion (CN⁻) acts as a ligand, and since there are three of them, it forms a coordination complex with the iron ion.
What is the correct name for pbclËÅ?
The correct name for the compound with the formula PbCl₄ is lead(IV) chloride. In this compound, lead (Pb) has a +4 oxidation state, which is indicated by the Roman numeral IV in its name. The chloride ions (Cl⁻) each carry a -1 charge, leading to the overall neutral charge of the compound.
What is the name of ionic compound BaCl2 using roman numerals?
The ionic compound BaCl2 is called barium chloride in the naming system without the use of roman numerals.
Why is it necessary to use Roman Numerals when writing a name for a compound?
Because some elements have different amounts of ions. The roman numerals are used to determine which ion is being used.
Why is it necessary to use Roman numerals in writing the name for the compound FeOH3?
It isn't.There are no Roman numerals in it.Fe = Iron (from Latin 'ferrum')O = OxygenH = Hydrogen3 = Arabic numeral.
What is the name for FeCl in roman numerals?
Chemical compounds are not named in Roman numerals!
What is the ionic compound name for K2S using roman numerals?
The ionic compound K2S is named potassium sulfide. Since potassium (K) has a fixed oxidation state of +1 and sulfur (S) typically has a -2 oxidation state, there is no need for Roman numerals in this case. Therefore, the name remains simply potassium sulfide without any Roman numeral designation.
What is the name of the Roman number system?
Roman Numerals
What state has four roman numerals?
The state that has four Roman numerals in its name is Massachusetts.
How do you put ionic compounds in roman numerals?
Roman numerals are used to represent the charge of the cation in an ionic compound. The Roman numeral is placed in parentheses after the name of the cation to indicate its charge. For example, in Fe(NO3)2, the Fe cation has a +2 charge, so it is written as iron(II).
How are oxidation state of transition metals indicated in the names of metal compound?
Romann numerals are used: (I), (II)...
Does copper require Roman numerals as part of its ionic compound chemical name?
No, copper does not require Roman numerals as part of its ionic compound chemical name. Roman numerals are used to indicate the charge of transition metals with variable oxidation states in ionic compounds. Copper typically has a fixed oxidation state of +2, so Roman numerals are not necessary.
Claudio in Roman Numerals?
The name Claudio cannot be formed from Roman numerals as, even if you replaced the letter 'u' with the numeral V, there is no Roman numeral with the symbol 'a.'
Do roman numerals appear in covalent compound?
No, Roman numerals are not used in covalent compounds. Roman numerals are used in the naming of ionic compounds to indicate the charge of a transition metal ion. In covalent compounds, the elements are combined through sharing of electrons and do not involve ions with specific charges.
