Difference between oxidation number and oxidation state
Answers
Answer:
Oxidation state and oxidation numbers are quantities that commonly equal the same value for atoms in a molecule and are often used interchangeably. Most of the time, it doesn't matter if the term oxidation state or oxidation number is used.
There is a slight difference between the two terms.
Oxidation state refers to the degree of oxidation of an atom in a molecule. In other words, oxidation state is the charge of an atom if all bonds it formed were ionic bonds. Each atom of the molecule will have a distinct oxidation state for that molecule where the sum of all the oxidation states will equal the overall electrical charge of the molecule or ion.
Each atom is assigned an oxidation state value based on predetermined rules based on electronegativity and periodic table groups.
If a molecule has a neutral charge, the sum of all oxidation states of its atoms must equal zero. For example, in the molecule FeCl3, each chlorine atom has an oxidation state of -1, while the iron atom has an oxidation state of +3. The three chlorine atoms cancel out the one iron atom, leaving a net charge of 0.
Oxidation numbers are used in coordination complex chemistry. They refer to the charge the central atom would have if all ligands and electron pairs shared with the atom were removed.

Answer:
For non coordination compounds Oxidation state refers to the charge the atom under study would have gained had the chemical bonds been completely ionic in nature. The oxidation numbers are the Roman numerical that are used to represent these oxidation states of atoms.
In the context of Coordination chemistry the term Oxidation number refers to the charge that the central metal atom would retain after all the ligands have been removed from it.
