A measure of the degree of oxidation of an atom in a substance. It is defined as the charge an atom might be imagined to have when electrons are counted according to an agreed-upon set of rules: (1) the oxidation state of a free element (uncombined element) is zero; (2) for a simple (monoatomic) ion, the oxidation state is equal to the net charge on the ion; (3) hydrogen has an oxidation state of 1 and oxygen has an oxidation state of -2 when they are present in most compounds. (Exceptions to this are that hydrogen has an oxidation state of -1 in hydrides of active metals, e.g. LiH, and oxygen has an oxidation state of -1 in peroxides, e.g. H2O2); (4) the algebraic sum of oxidation states of all atoms in a neutral molecule must be zero, while in ions the algebraic sum of the oxidation states of the constituent atoms must be equal to the charge on the ion. For example, the oxidation states of sulfur in H2S, S8(elementary sulfur), SO2, SO3, and H2SO4 are, respectively: -2, 0, +4, +6 and +6. The higher the oxidation state of a given atom, the greater is its degree of oxidation; the lower the oxidation state, the greater is its degree of reduction.

∙ 15y agoThere are multiple names for Iron Oxide (chemical formula Fe2O3).... ferric oxide, red iron oxide, synthetic maghemite, hematite, colcothar, and most commonly Iron Oxide is known as rust.
Iron oxide could also be known as rust, this is because oxide is like oxygen in the air and iron would be the mineral, when these two combine with high humidity levels rust is created.

The process of rusting is also called what?
The process in which metal rusts is called oxidation. This happens usually when water is present and the oxygen can bond with the metal releasing hydrogen into the air.
What is the oxidation state for 2I-?
The oxidation state of iron in two moles or atoms of elemental iron is zero. If you mean iron (II), the oxidation state is +2.
What caused by chemical reaction of iron and oxygen?
It forms iron oxide, a common compound generally referred to as rust.
What is the oxidation number of iron in brown ring complex?
The oxidation number for iron in FeBr3 is 3+.
What is the oxidation number of an iron atom in Fe3O4?
This is iron II, III oxide and features iron in both the 2+ and 3+ oxidation states.
What are boats covered in iron called?
Boats covered in iron are commonly referred to as ironclads.
What is chem oxidation?
If I understand your question correctly your are asking simply what oxidation is. This is just the process of adding oxygen. So oxidized iron for example is iron oxide, more commonly known as rust
What is the oxidation state of iron in Iron chloride?
There are two Iron chlorides. Iron(II) chloride, in which iron is in +2 oxidation state, and Iron(III) chloride, in which iron is in +3 oxidation state.
Number of oxidation iron III?
+3 is the oxidation no of iron(III)
What happens to iron with oxidation?
After oxidation iron is transformed in oxides.
What creates a series of oxidation reduction reactions?
The respiration of glucose creates a series of oxidation reduction reactions. This is the process leads that to the synthesis of adenosine triphosphate, more commonly referred to as ATP.
What does iron have to be exposed to for oxidation to occur?
Iron has to be exposed to oxygen for oxidation to occur.
The process of rusting is also called what?
The process in which metal rusts is called oxidation. This happens usually when water is present and the oxygen can bond with the metal releasing hydrogen into the air.
Why is oxidation bad?
oxidation is rust and rust weakens iron, iron is supposed to be strong, and therefore oxidation is bad.
What is rust the oxidation of?
Rust is the oxidation of iron. It is usually a reddish-brown and is fairly well attached
What is the oxidation state for 2I-?
The oxidation state of iron in two moles or atoms of elemental iron is zero. If you mean iron (II), the oxidation state is +2.
Can iron be in a wire?
Yes, iron could be made into a wire. However, because of its susceptibility to oxidation and lower conductivity than copper, this metal is not commonly used for electrical wires.
