What is Hydrogen?

Hydrogen is the first element of the periodic table.. hidrogeno elemento

It is the lightest chemical element that exists; the atom consists of one proton and one electron and is stable as a diatomic molecule (H2).

Under normal conditions hydrogen is in gaseous state, and is tasteless, colorless and odorless.

On Earth is abundant, it constitutes approximately 75% of matter in the universe, but is combined with other elements such as oxygen to form water molecules, or carbon to form organic compounds. Therefore, there is a fuel that cannot be taken directly from nature, but an energy carrier (like electricity) and therefore it must be “manufactured.”
