In chemistry, iron(II) refers to the element iron in its +2 oxidation state. In ionic compounds (salts), such an atom may occur as a separate cation (positive ion) denoted by Fe2+.Answer: Oxidation number of Fe in Fe₂(SO₄)₃ is +3. Explanation: We know that charge on SO₄ is -2. Le the oxidation number Fe be x.For atoms that can form multiple ions, the oxidation state is added to the name of the cation using Roman numerals. Therefore, you can say that iron is in the +2 oxidation state in the iron(II) cation, Fe2+ .

What is the oxidation state of iron in Fe3+?
The iron ion Fe3+, for example, has an oxidation number of +3 because it can acquire three electrons to form a chemical bond, while the oxygen ion O2− has an oxidation number of −2 because it can donate two electrons.
What is the oxidation number of Fe3+ and Fe2+ ions?
In naming compounds
You will have come across names like iron(II) sulfate and iron(III) chloride. The (II) and (III) are the oxidation states of the iron in the two compounds: +2 and +3 respectively. That tells you that they contain Fe2+ and Fe3+ ions. This can also be extended to negative ions.

What is oxidation number of Fe in FeO?
In Iron (II) oxide, or Ferrous Oxide, or FeO, the Iron element (Fe) is bonded to the Oxygen, in the oxidation state of “2”. This means that the Iron has accepted 2 electrons from the Oxygen. Because of this electromagnetic interaction, the charge of the Iron (Fe) in FeO is 2+.
What is the oxidation number of Fe in Fe3O4?
Hence, the oxidation number of Fe in Fe3O4 is 8 / 3.
Why is iron +2 or 3?
Ferrous oxide, commonly known as iron(II) oxide contains iron that lost 2 electrons in the oxidation process. So it is able to bond with other atoms that have an extra 2 electrons. Ferric oxide, is commonly known as iron(III) oxide. It contains iron that lost 3 electrons.

How many total electrons are in a Fe2+ ion?
Electron “cloud” of orbitals
For example, among atoms of iron, all with 26 protons, Fe2+ has 24 electrons and Fe3+ has 23 electrons, whereas elemental (uncharged) Fe has 26 electrons. the mass of an atom is outside the nucleus.
Is Fe 2 a cation?
The adjective ferric or the prefix ferri- is often used to specify such compounds — as in “ferric chloride” for iron(III) chloride, FeCl 3. The adjective “ferrous” is used instead for iron(II) salts, containing the cation Fe2+. The word ferric is derived from the Latin word ferrum for iron.
