What is the definition of oxidation?

-3. The sum of oxidation numbers of the atoms in all polyatomic ion is the net charge - its part of the definition of oxidation number. ...

zero. N2 is the elemental form of nitrogen and by definition a pure element has oxidation number zero. ...

The official definition of IUPAC is the following: "Oxidation state of an atom is the charge of this atom after ionic approximation of its heteronuclear bonds, (and the term oxidation number is nearly synonymous)". ...

Well it has less electrons than it had before. That is the definition of oxidation. The loss of electrons is oxidation. The gain of electrons is reduction. ...

A set of chemical treatment procedure design to remove organic and inorganic material in waste water by oxidation. ...

Either a oxidation or a reduction, depending on where the electrons are moving. ...

Oxygen, as Oxidation is the very definition of "burning".

Iron+water+oxygen Oxidation by chemistry definition does not always involve oxygen. EX: 2 Na + Cl2 --> 2 NaCl ...

An oxidoreductase enzyme that catalyzes the oxidation of phenols and other related substances. ...

zero- H2 is the elemental form- by definition the ON# is zero

The official definition of the word blackhead is "a plug of sebum in a hair follicle, darkened by oxidation."...

Pure diamond and pure graphite are composed only of elemental carbon; therefore, the oxidation number of the carbon atoms is 0 by definition. ...

Zero. In the elemntal stae all elemnts have an ON of zero by definition.

A metal that has incompletely filled d-orbitals in its ground state or in any of its oxidation states. ...

Bromine gas (or bromine in any other state of matter except plasma) is a chemical element, and the oxidation number of any element in its elemental state is zero by definition. ...

Yes, because an element is in oxidation state ZERO. A reaction is redox only when there is a change in oxidation state of relevant species. So if a compound is formed from elements (as opposed to other compounds) there by definition has to be a change in oxidation state. ...

The oxidation states of nitrogen, hydrogen and oxygen would be -I, +I and -II respectively. Often the terms oxidation number and oxidation state are used interchangeably. However the formal definition of oxidation number ligands are removed from the central atom (irrespective of electronegativity) with ALL bonding electrons. So in H2NOH choosing N as the central atom the oxidation numbers of nitrogen would be +III, H and OH would be -I. (This convention is usually applied to complexes where treating H as a hydride...

The chemistry definition of oxidation is the loss of electrons. Na atoms react by losing an electron, so they are being oxidized. ...

Rust - by definition - is oxidation. It requires oxygen. If it's exposed to nitrogen, it's not oxidizing. ...

Chemical oxygen demand is the necessary oxygen to be used in water chemical reactions (oxidation of iseveral impurities). ...

Co = +2 oxidation C = +4 oxidation O = -2 oxidation

This process is a natural alternative to pressure oxidation for process ores containing sulfides. In essence, bacteria oxidize and break down the sulfide minerals, freeing the occluded metal and making it more amenable to leaching. ...

Essentially oxidation is loss of electrons; oxidation is also combustion.

oxidation number of I is -1. oxidation number of F is +1.

Oxidation number is oxidation states of an element. It can be positive or negative. ...
