Hydrogen is indeed an element and the lightest element. A mixture of hydrogen and oxygen is highly explosive. However, hydrogen has three naturally occurring isotopes: Protium (¹H), Deuterium (²H or D), and Tritium (³H or T). They differ in the number of neutrons (0, 1, and 2 respectively) while all having one proton.
