What does a roman numeral after a transition metal in a chemical name mean?
WSS
What do Roman Numerals represent in chemistry?
The Roman numeral in the parentheses is the valence or oxidation of the metal that it follows. Transition elements have more than one oxidation number
When do need to use roman numeral in the name of a compound?
For the transition metals, the roman numeral designates the valence number of the metal in the ionic bond. For example CuSO4 is Copper (II) Sulfate, because the copper has a valence of +2 in this bond.
What does roman numeral tell you in an ionic bond?
The Roman numeral tells you the number of electrons a polyvalent cation (usually a transition metal) gives up to participate in the ionic bond. Example: "Iron (III) oxide" means the iron is giving up 3 electrons to form the compound Fe2O3.
Which metals would not use a roman numeral as part of its name in a compound?
Roman numeral is used to mark valence. If an atom, or metal atom has only one valence, you can spare writing it
When naming an ion of a transition metal that can have more then one possible ionic charge the numerical value of the charge is indicated by a?
Roman numeral placed in parentheses after the name of the transition metal.
What does a roman numeral after a transition metal in a chemical name mean?
WSS
What does a roman numeral tell you about transition metals?
Roman numerals in transition metal names indicate the oxidation state of the metal ion. This is important because transition metals can exist in multiple oxidation states, so the Roman numeral helps to specify which one is present in the compound.
What happens when a transition metal has more than one oxidation number?
Roman Numeral
When naming a transition metal ion that can hace more than one common ionic charge the numerical value of the charge is indicated by a?
Because transition metals can assume more than one charge, the transition metal ion is named by using a Roman numeral
How are transition metals named in metal compounds?
A roman numeral in parentheses follows the name of the metal... apex

When naming a transition metal ion that can have more than one common ionic charge the numerical value of the charge is indicated by a .?
Roman numerals are used: I, II, III.
How are oxidation states of transition metals indicated in the names of metals compounds?
The oxidation state of a transition metal in a compound is indicated by a Roman numeral in parentheses after the metal's name. For example, in FeCl3, iron is in the +3 oxidation state, so the compound is named iron(III) chloride. The Roman numeral helps identify the charge on the transition metal ion.
How is the oxidation state of a transition metal determined from the chemical formula?
The subscript of the second ion identifies the oxidation state of the transition metal
