Hydrogen
+1 in most of its compounds
-1 in metal hydrides and in hydrocarbons
In K2MnF6, +1 for K, +4 for Mn and -1 for F In SbF5, +5 for Sb and -1 for F In KSbF6, +1 for K, +5 for Sb and -1 for F In MnF3, +3 for Mn and -1 for F In F2, 0 for F
Hydrogen has an oxidation number of +1 in most of its compounds and -1 in metal hydrides and hydrocarbons.
In the compound H2S, hydrogen has an oxidation number of +1, and sulfur has an oxidation number of -2.
The oxidation number of hydrogen in NH3 is +1, and the oxidation number of nitrogen is -3. This is because hydrogen typically has an oxidation number of +1 and in compounds, nitrogen usually has an oxidation number of -3.
The oxidation number of H+ is +1. This is because hydrogen typically has an oxidation number of +1 when it forms an ion by losing its single electron.
The oxidation number of each hydrogen (H) in H3O+ is +1. The oxidation number of oxygen (O) is -2. Overall, the oxidation number of the H3O+ ion is +1.
The oxidation number of hydrogen is +1 when combined with nonmetals, and -1 when combined with metals.
Hydrogen has an oxidation number of +1 in most of its compounds and -1 in metal hydrides and hydrocarbons.
The oxidation number of chlorine in KCl is -1. This is because potassium (K) has an oxidation number of +1 and the overall compound is neutral, so the oxidation number of chlorine must be -1 to balance the charge.
In KMnO4, Mn has an oxidation number of +7, KNO2 has N with an oxidation number of +3, and H2SO4 has S with an oxidation number of +6. In MnSO4, Mn has an oxidation number of +2, H2O has O with an oxidation number of -2, KNO3 has N with an oxidation number of +5, and K2SO4 has S with an oxidation number of +6.
Because they have one valence electrons, and if they lose this electron they attain an oxidation number of +1
Sodium - it goes from oxidation number 0 to +1
