Answer:
The oxidation number of Hydrogen is +1 except in hydrides like NaH,
The oxidation number is basically the count of electrons that atoms in a molecule can share, lose or gain while forming chemical bonds with other atoms of a different element.
Oxidation number of hydrogen
H (Z= 1) = 1s1.
- In hydrides like NaH, H occurs in −1 state.
- Whereas in acids as well as oxides, H occurs in +1 state.
- The Oxidation state of Hydrogen is 1+ when in a regular compound.
- Hydride like NaH, here the oxidation state of H is -1 as metals are more electropositive than hydrogen.
