Reactions with Oxygens

what is a reaction between a metal and oxygen called?
Have you studied redox chemistry yet?

If a metal reacts with oxygen, it is just called a metal oxide in general. the name of the metal comes first, oxide as ending as last. If metals react with oxygen. There are also ones which don't tend to do.

Thnx a lot so useful :smile:

Oxidisation look up redox in your text book

It's more than oxidation. That only describes what is happening to the metal. It does not describe the reaction accurately.

@varunthegreat1 when you study redox you will get the answer to your question.

Ok yes there is also reduction taking place and loss/gain of electrons - he was just asking for the name given to that reaction and it would be oxidisation

I believe that "oxidation" would fail to pick up the mark in an exam. You might as well call it a reduction. Both only tell half the story and both are not answering the question.

The reaction is not an oxidation, although it includes one.
As you say, there is a reduction involved too - there has to be - so describing the reaction as an oxidation is not going to get marks in an exam.

We would say the metal undergoes oxidation, but not that the overall reaction of metal and oxygen is an oxidation. Equally the oxygen undergoes reduction. We can't have oxidation without reduction, and vice versa.

The overall reaction involves oxidation and reduction so it a redox reaction.

Don’t know what past papers you have seen that want redox as an answer. If it was an explain answer then yes you would need to explain oxidation and the loss of electrons and vice versa but if it simply asks what type of reaction (1 marker) and it is clearly talking about the reaction in regards to the metal ( as they often do) then putting redox actually won’t credit you the marks as it specifically wants oxidation or reduction ( oxidation in this case) this is going off of past paper markchemes, and I am yet to see an explain the oxidation and reduction type question as they usually ask it in regards to the Production of pure iron (Iron Furnace questions).

So, in the originally posted question, what is happening to the oxygen?
The question is about the reaction, not the metal only.
