Hydrogen.
+1 in most of the compounds
-1 in metal hydrides
2-
hydrogen has three oxidation states.They are plus 1 zero and -1
as oxidation number of K is 1 and the molecule is neutral 1+ Cl=0 Cl= -1 Therefore, the oxidation number of Cl is -1
+1 for H+ ion
Sodium - it goes from oxidation number 0 to +1
Hydrogen has an oxidation number of +1 in most of its compounds and -1 in metal hydrides and hydrocarbons.

Hydrogen has an oxidation number of +1 in most of its compounds and -1 in metal hydrides and hydrocarbons.
+1 for H+ ion
Sodium - it goes from oxidation number 0 to +1
Because they have one valence electrons, and if they lose this electron they attain an oxidation number of +1
nitrogen is -3 H is plus 1
No. Fluorine has only two oxidation states. 0 in F2 and -1 in fluoride ion
oxidation number of I is -1. oxidation number of F is +1.
-2 for O +1 for each H
