Its oxidation number is -1, which is uncommon for hydrogen.
The oxidation number of Na in NaH is +1 because alkali metals like Na typically have a +1 oxidation state in compounds. The oxidation number of H in NaH is -1 because hydrogen usually has a -1 oxidation state when bonded to metals.
Hydrogen can be + 1 or -1 when it forms hydrides.
In the compound hydrides such as lithium hydride (LiH) or sodium hydride (NaH), hydrogen has an oxidation number of -1.
The oxidation number of H in NaH is -1. Sodium (Na) typically has an oxidation number of +1, so in order for the overall compound to be electrically neutral, hydrogen (H) must have an oxidation number of -1.
No, the oxidation state of hydrogen in CaH2 is -1. In this compound, calcium is in the +2 oxidation state, so hydrogen must be in the -1 oxidation state to balance the charge.

In NH4F, nitrogen has an oxidation state of -3, hydrogen has an oxidation state of +1, and fluorine has an oxidation state of -1.
O = -2 oxidation state H = +1 oxidation state
The oxidation state of F in HOF (hydrogen monofluoride) is -1. Hydrogen is typically assigned an oxidation state of +1, leaving the fluorine with an oxidation state of -1.
Hydrogen can exhibit a negative oxidation state in compounds known as hydrides, where it gains an electron to become H-. Some examples include metal hydrides like sodium hydride (NaH) and covalent hydrides like borane (BH3).
In the compound HF, the oxidation number of hydrogen (H) is +1 and the oxidation number of fluorine (F) is -1. This is because fluorine is more electronegative than hydrogen, so it takes on a -1 oxidation state while hydrogen takes on a +1 oxidation state.
In MgH2, since magnesium is always assigned a +2 oxidation state and hydrogen typically has a -1 oxidation state, the oxidation number of hydrogen in MgH2 is -1.
The oxidation state of hydrogen is usually +1, except in metal hydrides where it can be -1.
