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.

What does the roman numeral tell about an element?
Roman numerals are used to identify the oxidation state of transition metals with more than one possible oxidation state.
In Iron III sulfate what does the roman numeral tell us?
That the charge of iron is +3 resulting in a formula of Fe2(SO4)3
In a stock name such as iron III sulfate the roman numeral tell us?
The total positive charge of the cation, which is the iron ion in this case.
What is a numeral used to tell how many times a number or variable is used as a factor?
An exponent is a numeral used to tell how many times a number is used as a factor.
What does a roman numeral tell you when it is written after an element?
I think it means how many atoms is in the element im not quite sure if im right or wrong it's just a guess off the top of my head.
How to tell if a bond is ionic or covalent?
if you have a metal and non metal bonding it's an ionic bond and if it's two non metals it would be a covalent bond.
Tell you the number 100 in roman numeral?
C
What does a roman numeral tell you about transition metals?
formula?
What kind of bond is Na plus I2?
The bond formed between the two is an Ionic bond. You can tell by using the difference in the elements electronegative, or just know the general trend that a metal and nonmetal form an ionic bond.
How can you tell an ionic bond is formed between magnesium and oxygen?
it is ionic bonding because magnesium is a metal and oxygen is not. ionic bonding occurs between a metal and non-metal
By seeing a chemical formulae how to tell which bond is existing in that?
H2o is having hydrogen bond but h+ and oh- also we are indicating why we can't say are ionic bond?
How can you tell that ionic bonding will placebetween metals and non metals?
Most of the time the bond between a metal and a nonmetal is ionic. However, there are some exceptions, such as BeCl2, which is covalent. The difference in electronegativity determines what kind of bond will form. Metals and nonmetals with a difference in electronegativity of >1.6 are considered to have an ionic bond.
What does the roman numeral tell about an element?
Roman numerals are used to identify the oxidation state of transition metals with more than one possible oxidation state.
What is the boiling point of an ionic bond?
Chemicals have boiling points, bonds do not. But let us say, you are asking what the boiling point is of a chemical that has an ionic bond. Again, not all ionic type chemicals (which are generally called salts) have the same boiling point. I can, however, tell you that the boiling point of a salt tends to be very high, in the thousands of degrees.
In Iron III sulfate what does the roman numeral tell us?
That the charge of iron is +3 resulting in a formula of Fe2(SO4)3
Ionic bonding vs covalent bonding?
An Ionic bond is one where an element gives away electrons to another, forming Ions. It usually occurs between metals and nonmetals. Another way to tell is if the electronegativity difference between the elements is greater than 2.0 then it is an ionic bond. A covalent bond is one where the elements share electrons with one another. It usually occurs between nonmetals. If the electronegativity difference between the elements is 2.0 or less it is a covalent bond.
Is BaO ionic or molecular?
No. One way to tell is that Ba and O are on opposite sides of the periodic table, and Ba is a metal and O is a nonmetal. We can also determine the difference in electronegativity. A difference of >1.6 is generally considered as ionic. The electronegativity of Ba is 0.89 and of O is 3.44. 3.44 - 0.89 = 2.55, so the bond is ionic.
