The oxidation number for hydrogen in a neutral atom is 0.
The central carbon atom has an oxidation number of -2 (O is -2, H is +1)
The oxidation number for boron in B2H6 is +3, and the oxidation number for hydrogen is -1. Each boron atom has an oxidation number of +3, and each hydrogen atom has an oxidation number of -1 in the B2H6 molecule.
In AsH3, arsenic (As) has an oxidation number of -3 since hydrogen (H) is always assigned an oxidation number of +1 in compounds.
The oxidation number of hydroxide (OH-) is -1. This is because oxygen typically has an oxidation number of -2, and hydrogen has an oxidation number of +1. In this case, there is one oxygen atom and one hydrogen atom, resulting in an overall oxidation number of -1.
The oxidation number of the sulfur atom in H2S is -2. Hydrogen is assigned an oxidation number of +1, and since the overall molecule has no charge (neutral), the oxidation number of sulfur must be -2 to balance the charges.

In disodium phosphate (Na2HPO4), each sodium (Na) atom has an oxidation number of +1 since it is in Group 1 of the periodic table. The hydrogen atom (H) has an oxidation number of +1, and the phosphate ion (PO4) as a whole has a charge of -3, making the phosphorus atom (P) have an oxidation number of +5.
The oxidation number for H is almost always 1+.
The oxidation number of hydrogen (H) in H2SO4 is +1.
H2SO4 is a compound and as such does not have an oxidation number. The individual atoms in this compound have oxidation number +1 for each hydrogen atom, +6 for sulfur, and -2 for each oxygen atom.
The oxidation number for H in H4P2O7 is +1. Each hydrogen atom has an oxidation number of +1 because it is bonded to more electronegative elements like P and O, which have higher electronegativity values.
The oxidation number of hydrogen in InH3 is +1. In compounds, hydrogen usually has an oxidation number of +1, as it has a tendency to lose its single electron to form a positive charge.
The oxidation state (or number) is zero. This is true for any element in any of its allotropic elemental forms.
