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.
Tell you the number 100 in roman numeral?
C
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 to tell if a bond is ionic or covalent?
One way to determine if a bond is ionic or covalent is to look at the electronegativity difference between the two atoms. If the difference is large (greater than 1.7), the bond is likely ionic. If the difference is small (less than 1.7), the bond is likely covalent. Additionally, ionic bonds typically form between a metal and a nonmetal, while covalent bonds form between two nonmetals.
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 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 does the oxidation number tell about an ionic bond?
The oxidation number of an element in an ionic bond indicates its charge when it gains or loses electrons to achieve a stable octet. By comparing the oxidation numbers of the elements involved, you can determine how many electrons each element has gained or lost in the formation of the bond.
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.
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.
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.
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.
