Oxygen in hydroxide has the oxidation number -2. This combines with the oxidation number +1 of hydrogen to form an anion with net charge of -1.
Its oxidation number is -1, which is uncommon for hydrogen.
Usually the oxidation no of oxygen is -2 and the oxidation no of hydrogen is +1 in a compound.
The ammonium ion has net charge of +1. The central nitrogen atom is bonded to four hydrogen atoms which have oxidation status +1. The oxidation number of nitrogen is -3 after balancing the charges.
In H2PO4-, oxygen has the formal oxidation number -2, phosphorus has the formal oxidation number +5, and hydrogen has the formal oxidation number +1. The formal oxidation numbers for oxygen in almost all oxyanions and for hydrogen in almost all acid anions have these values, so that the remaining element can be assigned a formal oxidation number by the requirement of satisfying the total electrical charge if any shown in the formula.

Contrast hydrogen don't exist. Hydrogen oxidation numbers are +1 and -1.
Hydrogen gas (H2) Oxidation number is 0. Hydrogen (H+) is +1.

Hydrogen dioxide is water and the oxidation numbers are +1 for each hydrogen and -2 for oxygen
As a diatomic element, it would be neutral and = 0Refer to this site for other rules:http://www.brynmawr.edu/Acads/Chem/Chem103lc/GCoxidationnumber.htmlThe oxidation number of NO, nitrogen oxide, is +2.
It is calculated by the relative electronegativity. Let's take HCl as an example. Chlorine is the more electronegative element, which partially attracts the electron shared by hydrogen. Hydrogen has partially donated an electron. Therefore in HCl, hydrogen and chlorine have +1 and -1 oxidation numbers respectively.
Oxidation and reduction in terms of hydrogen transferOxidation is loss of hydrogen.Reduction is gain of hydrogen.
Hydrogen takes +I and fluorine takes -I oxidation states in hydrogen fluoride.
