Question

What is the oxidation number of H?

Answer 1

1. The oxidation state or oxidation number is defined as the loss or gain of electrons in an atom, molecule, or compound to achieve a stable configuration.
2. The atomic number of Hydrogen is 1.
3. The general electronic configuration of Hydrogen is $1{\mathrm{s}}^1$.
4. Hydrogen can act as an electron donor as well as an electron acceptor.
5. The oxidation number of Hydrogen can vary from -1 to +1.
6. In Hydrides such as Sodium hydride$\left(\mathrm{NaH}\right)$the oxidation number of Hydrogen is -1.
7. In acids and oxides, the oxidation number of Hydrogen is +1 like in HCl.
