HTO
correct, formula, see observation
OBS

This happens when a tritium atom replaces a hydrogen atom in water (H2O) to form HTO. HTO has the same chemical properties as water and is also odourless and colourless.

OBS

Chemical formula: HTO

Tritium is a hydrogen atom that has 2 neutrons in the nucleus, in addition to its single proton, giving it an atomic weight near 3. Although tritium can be a gas, its most common form is in water, because, like non-radioactive hydrogen, radioactive tritium reacts with oxygen to form water. Tritium replaces one of the stable hydrogens in the water molecule, H2O, and is called tritiated water. Like H2O, tritiated water is colorless and odorless. Tritium has a half-life of 12.3 years and emits a very weak beta particle.

CONT

-Eau tritiée (HTO). Légèrement plus lourde que l'eau légère H2O, c'est la forme la plus abondante du tritium dans le milieu naturel et les espèces vivantes. La différence de masse entre les composés H et T se manifeste dans les processus naturels de changement de phase tels que l'évaporation, la condensation ou la solidification, et entraîne un faible enrichissement du tritium par rapport à l'hydrogène léger dans la phase condensée.
