WebApr 8, 2024 · Properties. Deuterium forms chemical bonds that are stronger than regular hydrogen.The triple point, boiling point, vapor pressure, heat of fusion, and heat of evaporation of deuterium are all much higher than those of common hydrogen. The gas deuterium is colorless. When ionized, however, it gives off a distinctive pink hue. Deuterium occurs in trace amounts naturally as deuterium gas, written 2 H 2 or D 2, but most of the naturally occurring deuterium atoms in the Universe are bonded with a typical 1 H atom to form a gas called hydrogen deuteride (HD or 1 H 2 H).
