Reduction and oxidation of Hydrogen 

After all this talk of oxidation and reduction there is still one more element to learn.

We know:

1. An element that has a loss of an electron is oxidation.
    An element that has a gain of an electron is reduction.

2. Oxidation is an element that gains oxygen.
    Reduction (reduced oxygen) is the loss of oxygen.

But, confusingly:

3. Oxidation is an element that loses  hydrogen.
    Reduction is an element that gains hydrogen.

Therefore, oxidation and reduction and oxygen and hydrogen are opposites.
