Note
A plural that appears once hydrogen stops being a substance and becomes something you can count. Naming the element or the gas, hydrogen usually works as a mass noun. The plural counts atoms in a structure, molecules of H₂, separate samples, or isotopic kinds, such as protium set beside deuterium and tritium. Chemists mostly mean atoms: a carbon carries three hydrogens, and a reaction may replace one.
