Definitions of hydrogen

  1. a nonmetallic univalent element that is normally a colorless and odorless highly flammable diatomic gas; the simplest and lightest and most abundant element in the universe
  2. A gaseous element, colorless, tasteless, and odorless, the lightest known substance, being fourteen and a half times lighter than air ( hence its use in filling balloons), and over eleven thousand times lighter than water. It is very abundant, being an ingredient of water and of many other substances, especially those of animal or vegetable origin. It may by produced in many ways, but is chiefly obtained by the action of acids ( as sulphuric) on metals, as zinc, iron, etc. It is very inflammable, and is an ingredient of coal gas and water gas. It is standard of chemical equivalents or combining weights, and also of valence, being the typical monad. Symbol H. Atomic weight 1.
  3. Hydrogen. The first chemical element in the periodic table. It has the atomic symbol H, atomic number 1, and atomic weight 1. It exists, under normal conditions, as a colorless, odorless, tasteless, diatomic gas. Hydrogen ions are PROTONS. Besides the common H1 isotope, hydrogen exists as the stable isotope DEUTERIUM and the unstable, radioactive isotope TRITIUM.
  4. A colorless, gaseous, inflammable substance, which becomes liquid under great pressure, and is the lightest element yet known, much lighter than air; when combined with oxygen it produces water.
  5. An odorless, colorless, tasteless element, gaseous at ordinary temperatures and pressure; symbol H, atomic weight 1. It is the lightest known substance, and the weight of one of its atoms is the unit of atomic weights. It is readily replaceable in many compounds by other elements or radicals, and this substitution of the hydrogen atoms in an acid forms a salt.
  6. A light gas, producing water upon oxidation.
  7. A gas which in combination with oxygen produces water, an elementary gaseous substance, the lightest of all known substances, and very inflammable.
  8. A gas, one of the elements of water, and the lightest substance known.
  9. Hydrogenous.
  10. A colorless, odorless, tasteless, gaseous element, the lightest substance known.
  11. A highly inflammable gas, constituting one of the elements of water, and the lightest of aeriform bodies.
  12. A gaseous body, and the lightest of all known bodies- called also inflammable air, and producing water when combined with oxygen.
