NOUN
-
the degree of oxidation of an atom or ion or molecule; for simple atoms or ions the oxidation number is equal to the ionic charge
the oxidation number of hydrogen is +1 and of oxygen is -2
How To Use oxidation number In A Sentence

- the oxidation number of hydrogen is +1 and of oxygen is -2
- The oxidation number of the halogens other than fluorine is - 1, unless they are bonded to oxygen or a more electronegative halogen.
- An indication of oxidation numbers or formal charge in Lewis structures and the resulting mesomeric structures is important in some branches of chemistry.
- A species is oxidized in a reaction if it undergoes a increase in oxidation number.
- The sum of oxidation numbers for all atoms in a polyatomic ion equals the charge on the ion, and the sum of all oxidation numbers for atoms in a neutral molecule equals zero.
- In the case of binary covalent compounds, the positive oxidation number is assigned to the more electropositive element, and the negative oxidation number to the more electronegative element.
- In organic chemistry it is thus more convenient to describe carbon in terms of its valency than its oxidation numbers.
