He categorized them into two types, based on whether or not lines of the element hydrogen appeared in the supernova spectrum.

A fuel cell converts the element hydrogen into electricity by chemically mixing it with oxygen, from which results water.

Solid hydrogen is the solid state of the element hydrogen, achieved by decreasing the temperature below hydrogen's melting point of 14.01 K ( 259.14 C).

Liquid hydrogen (LH2 or LH) is the liquid state of the element hydrogen.

The element hydrogen has three isotopes known respectively as hydrogen, deuterium, and tritium.
