But when it gives up its one valence (outer) electron (symbolized by e −), it becomes a sodium ion Na + with an oxidation state of +1. its better we call oxidation state rather than oxidation number. Oxidation number, also called oxidation state, the total number of electrons that an atom either gains or loses in order to form a chemical bond with another atom.. Each atom that participates in an oxidation-reduction reaction is assigned an oxidation number that reflects its ability to acquire, donate, or share electrons. H has a charge of +1 so again, the oxidation number is +1. LOGIN TO POST ANSWER. Chemistry. Since Sodium peroxide is a neutral molecule, its net charge is zero. What Is The Oxidation Number. It normally has an oxidation state of +1, and its single valence electron is lost with great ease, yielding the colourless sodium cation (Na +). 5 years ago. hope you understand Vikramkumat Vikramkumat that sodium has +1 oxidation state we say that nitrogen has an oxidation number of -1/3 in NaN3. C-2. the sodium, Na+, ion and the disulfide, [S2O5]2-, ion. Both hydrogen and oxygen have a possibility of 2 different oxidation numbers depending on to what they are bonded. Oxidation state (or oxidation number) refers to the number of electrons added to or removed from an element when it forms a chemical compound. Source(s): https://shrink.im/a8X6U.
