Zero The oxidation number of an element in any of its elemental forms (allotropes) is always zero
Oxidation number of h is 2
Oxidation number of o is -2. Oxidation number of H is +1.
The central carbon atom has an oxidation number of -2 (O is -2, H is +1)
The oxidation number is +1. (Oxidation number for an ion is the ionic charge)
Water, or H2O is a free-standing neutral compound, so it's oxidation number is 0. Its atoms have oxidation number though. Hydrogen's oxidation number in water is +1, and oxygen's is -2.

Water, or H2O is a free-standing neutral compound, so it's oxidation number is 0. Its atoms have oxidation number though. Hydrogen's oxidation number in water is +1, and oxygen's is -2.
The oxidation number for H is almost always 1+.
+1 for H -2 for O
+1 for H +5 for P -2 for O
The oxidation number for H is +1, and the oxidation number for O is -1.
-2 for oxygen +1 for each H
-2 for O and +1 for H
The oxidation state (or number) is zero. This is true for any element in any of its allotropic elemental forms.
