hydrogens

Water's gaseous components

Hydrogens is the plural of hydrogen, the lightest and most abundant element in the universe.

The plural appears in scientific contexts discussing different forms or isotopes: The three hydrogens—protium, deuterium, and tritium—have different nuclear properties.

In chemistry, it may refer to hydrogen atoms in a molecule: The molecule has four hydrogens attached to the carbon.
