Oxidation state or oxidation number: Meaning and …

The oxidation number of an element in a free atomic state (Na, H, Cl, O, P etc) or in its poly-atomic state (graphite, H 2, Cl 2, O 2 etc) is always zero. The oxidation number of hydrogen is always +1 in its compounds. However, in metal hydrides like NaH, MgH 2 etc. the oxidation number of hydrogen is -1 because metals are more electropositive than hydrogen.
