Hydrogen is a chemical element. It has the symbol H and atomic number 1. It has a standard atomic weight of 1.008, meaning it is the lightest element in the periodic table. ... Hydrogen's most common isotope has one proton with one electron orbiting around it.
Hydrogen fuel can be produced from methane or by electrolysis of water.
