$a The first chemical element in the periodic table with atomic symbol H, and atomic number 1. Protium (atomic weight 1) is by far the most common hydrogen isotope. Hydrogen also exists as the stable isotope DEUTERIUM (atomic weight 2) and the radioactive isotope TRITIUM (atomic weight 3). Hydrogen forms into a diatomic molecule at room temperature and appears as a highly flammable colorless and odorless gas. $8 eng 450 $a Protium $5 e $8 eng 450 $a protium $5 e $8 slo 450 $a hydrogénium $5 e $8 slo 686 $a D01.268.406 686 $a D01.362.340 750 $a Hydrogen $8 eng 801 -0
