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.

Rust is formed as a result of oxidation of which metal?
Rust is formed as a result of oxidation of iron (Fe) metal.
What is irons oxidation number?
The oxidation number of iron can vary, but it is commonly found at +2 or +3. In some compounds, like Fe2O3, iron is in the +3 oxidation state, while in others, like FeO, it is in the +2 oxidation state.
If you add iron and oxygen?
If you add iron and oxygen, the iron will undergo a chemical reaction called oxidation, forming iron oxide, commonly known as rust. This process occurs more rapidly in the presence of moisture, as water facilitates the oxidation of iron.
What caused by chemical reaction of iron and oxygen?
The chemical reaction of iron and oxygen forms iron oxide, commonly known as rust. This process is known as oxidation, where iron atoms react with oxygen molecules to create iron oxide, which appears as a red-brown substance on the surface of the iron.
What name do you usually give to iron oxide?
Iron oxide is commonly referred to as rust.
Rust is formed as a result of oxidation of which metal?
Rust is formed as a result of oxidation of iron (Fe) metal.

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.
What is an iron ore called?
Iron ore is commonly referred to as hematite, magnetite, or taconite, depending on its composition and characteristics.
Iron combines with oxygen in the air and causes?
Iron combines with oxygen in the air through a process called oxidation, which results in the formation of iron oxide, commonly known as rust. Rust weakens iron structures over time, causing them to corrode and deteriorate.
What happens to iron with oxidation?
After oxidation iron is transformed in oxides.
What chemical weathering process is caused by oxygen and water acting on iron?
The chemical weathering process caused by oxygen and water acting on iron is called oxidation. This process results in the formation of iron oxide, commonly known as rust.
