The charge. Cations and anions have an oxidation number equal to their charge, for example in Fe2+, Fe hasan oxidation number of +2 and in S2- S has an oxidation number of -2. Uncharged atoms have zero oxidation number.
The oxidation number of an atom means how many electrons an atom will gain or lose to become stable. It needs to end up with eight valence electrons to have a full octet, and be stable. It will either gain or lose electrons to get to that amount.
The oxidation number of a monatomic ion is equal to its charge.
For example a 2+ ion (e.g. Ca2+ or Fe2+) has a 2+ oxidation state while a 1- ion (e.g. F-) has a 1- oxidation state.
The oxidation number of a monatomic ion is equal to its charge.
For example a 2+ ion (e.g. Ca2+ or Fe2+) has a 2+ oxidation state while a 1- ion (e.g. F-) has a 1- oxidation state.
It varies depending on the ion. The oxidation number of a monatomic ion equals the charge of the ion.
For example, the oxidation number of Na+ is +1; the oxidation number of N3- is -3.
Yes, it is
oxidation number ^o.o^
No: An oxidation number, if shown at all in a chemical formula, is shown with a superscript. The oxidation number is usually shown only for monatomic ions.
If an atom loses electron, then it will have a positive oxidation number. If an atom gains electron, then it will have a negative oxidation number.
Species doesn't exist
An element's oxidation number indicates how many electrons an atom has gained, lost, or shared to become stable.
It is equal to the charge. Oxidation number depends on charge.
Yes. it is
Oxidation Number

No: An oxidation number, if shown at all in a chemical formula, is shown with a superscript. The oxidation number is usually shown only for monatomic ions.
In most cases it is the value of its charge, but not always.
If an atom loses electron, then it will have a positive oxidation number. If an atom gains electron, then it will have a negative oxidation number.
The O in oxides always has oxidation number -2 (except for in peroxides where it is -1). Since the overall species has oxidation number 0, Mg must also have oxidation number +2.

An element's oxidation number indicates how many electrons an atom has gained, lost, or shared to become stable.
Oxidation number describes gain of electrons. It involves addition of oxygen and removal of hydrogen.
