Oxidation number of Sodium is +1 when Sodium exists as Sodium ion. and the Oxidation number of Sodium metal is zero.

0 as the pure metal, but said metal is highly electropositive and will happily donate its outer valence electron to form the stable Na+ cation (which then has a full outer valence shell of 8, which is highly stable). In this state, its oxidation number is +1

Of elemental sodium…? Its oxidation number is ZERO…. And by definition, the oxidation number is the charge left on an atom when all the bonding pairs of electrons are removed with the charge, the electron, retained by the most electronegative atom. Elements have ZERO oxidation state by this criterion, as it has neither been reduced (gained electrons) nor oxidized (lost electrons)…

Sodium metal is commonly oxidized to give a +I oxidation state in its salts and compounds…

[math]Na → Na^{+} + e^{-}[/math]

Oxidation number of Na is zero if it is in free state. But if it is present in combining state like NaCl then its oxidation number is +1. Na is the member of group 1 ( alkali metals) of modern periodic table .Due to presence of one valance electron , all the members of group 1 always show +1 oxidation state in their corresponding compounds.

Sodium is highly Electropositive and has only 1 electron in its outermost shell, hence exhibits only +1 oxidation state in all of its compounds.

Hope it helps.

Cheers!!

Sodium exhibits only the +1 oxidation state in compound formation.

This highly electropositive and reactive metal usually forms ionic compounds in +1 state.

For sodium atom oxidation state is 0 and for Na+ oxidation state is +1
