oxygen compound=p
Usually the oxidation no of oxygen is -2 and the oxidation no of hydrogen is +1 in a compound.
Minimum oxidation number: -3, Maximum oxidation number: 5
In most compounds oxygen will have an oxidation state of -2. The only exceptions are peroxides (-1), superoxides (-1/2), and compounds in which oxygen bonds with fluorine (+1 or +2).
Carbon has an oxidation number of +4 in both carbonate and bicarbonate. Oxygen as usual has an oxidation number of -2, and hydrogen has an oxidation number of +1. Therefore, the ion CO3-2 has six negative charges from oxygen partly balanced by four positive changes from carbon for a net of -2, and HCO3-1 has six negative charges from oxygen partly balanced by one positive from hydrogen and needs for plus four from carbon for an overall value of -1.
This is the usual formula for elemental oxygen in its gaseous state. It could also be called a "diatomic oxygen molecule."

+1 for hydrogen in most of the compounds and -1 in hydrides and hydrocarbons
This is the usual formula for elemental oxygen in its gaseous state. It could also be called a "diatomic oxygen molecule."
+1 for K -2 for each O +7 for I
CuO ==== One atom of copper. One atom of oxygen. ( assuming the usual 2 oxidation state of copper )
When hydrogen and oxygen are kindled in the right quantities, then we mostly don't call the product a mixture. Rather we call it a compound. The most usual compound of hydrogen and oxygen is water. Its not important that the compound should have the properties of its constituting elements. If we that water as an example, then we all know that water is a non supporter of combustion whereas hydrogen and oxygen are highly inflammable gases.
Oxidation is the usual cause of discoloration when an iron is exposed to air. The atoms on the surface of the metal react with Oxygen in air to produce a metal oxide.
The usual state of oxygen and hydrogen: they are gases at room temperature.
The rule for hydrogen is that it normally has an oxidation state of +1, EXCEPT in metal hydrides, when it has an oxidation state of -1.Li is a metal, LiH is a metal hydride.Does that tell you what you need to know?
