When hydrogen reacts with active metals, it shares electrons
gains one electron
loses one electron
O loses two electrons

Atomic hydrogen is very reactive. It combines with most elements to form hydrides (e.g., sodium hydride, NaH), and it reduces metallic oxides, a reaction that produces the metal in its elemental state. ... Almost all metals and nonmetals react with hydrogen at high temperatures.

"electrical energy" transforms to "thermal energy".hope my answer has you : )

If this is a true or galse then its true but if not then what is the question?
