No, sometimes water is involved, which is another thing that can create rust.

How can you justify that a reaction between magnesium and oxygen is a redox reaction whioe the reaction shows only addition of oxygen?
In any redox reaction, at least one reactant is reduced and at least one reactant is oxidized. In the reaction between magnesium and oxygen, the magnesium atoms are oxidized because they lose electrons and the oxygen atoms are reduced because they gain electrons. Furthermore, the premise of the question is erroneous: The reaction does not as alleged show only addition of oxygen; instead it shows combination of magnesium and oxygen to form a new chemical entity, the compound magnesium oxide.
What is rusting reactivity?
The reaction which occurs between a metal and oxygen producing rust is an oxidation-reduction reaction. The metal is oxidized, as it loses electrons, while oxygen is reduced because it gains electrons. The result is various metal oxides, commonly known as rust.
Will iron only rust if oxygen and water are presented?
Important is only the oxygen.
Why does metal rust and what is the chemical reaction for rusting?
== == Being a layman, this answer will be a lay answer, until a chemist can improve it. The word rust is often used generically to describe the corrosion of several metals, BUT in actuality, ONLY IRON, or metal alloys containing IRON can rust. Most metal do corrode, but the term rust applys only to ferrous [iron] metals. The rusting of iron is an oxidation-reduction type of chemical reaction whereby oxygen combines with the outer region of the iron containing metal.
Why does a rusty nail weigh more than the original nail?
Rust is iron oxide, a molecule consisting of iron and oxygen. The mass of the iron in the rust molecules comes from the original nail, but the mass of the oxygen has come from the air. When rust forms on iron, the mass of the iron object is increased by the mass of the oxygen that has combined with some of the iron.
What tells you that iron oxide is a chemical compound?
The name indicates that it is an oxide of iron, which would only result from a chemical reaction between iron and oxygen, forming the compound iron oxide.
What similarities iron have a similar reaction with water as potassium?
Potassium react violent with water, iron react only if oxygen is present.
What is rust and how does it form?
Rust forms when metals containing iron mix with the oxygen in the air or the water and create a compound named iron oxide. This compoumd has water molecules, so we call it a hydrated compound. Chemically and very simply speaking, iron atoms lose a few electrons to oxygen atoms. This process, where electrons are lost from atoms, is the oxidation process. When oxidation occurs it produces a chemical reaction that creates iron oxide
How can you justify that a reaction between magnesium and oxygen is a redox reactionwhile the reaction shows only addition of oxygen?
Magnesium loss electrons and oxygen gain electrons.
How can you justify that a reaction between magnesium and oxygen is a redox reaction w hile the reaction shows only addition of oxygen 2mg plus O 2mgo?
Oxidation is a redox reaction.
Why does gold not rust?
Rust is the common name of the corrosion products of Iron. These are the results of the reaction of iron with water and oxygen. Rust is also the term used only for iron oxides (Iron which reacts with oxygen). For corrosion of gold, see related link below. == ==
Does iron react with cold water?
The iron is rusting because of its chemical bonding with oxygen, which creates ironoxide.

Does rusting of iron require the presence of oxygen and water for it to occur?
No. Only oxygen must be present. The process of rusting is the reaction of iron metal (Fe) combining with oxygen gas (O2) to form iron oxide (FeO or Fe2O3). Water (and salt) speed up this reaction a great deal, but oxygen is the only one that is necessary.

Why there is no water formation in the neutralisation reaction between ammonia and HCl?
Water is only formed if there is oxygen atom present and in this reaction no oxygen atom is present. Rather than neutralisation it is a combination reaction in which ammonia and HCl combine to produce ammonium chloride.
