The half-life is the time that it will take for half of the atoms in a sample of a radioactive isotope to decay into another element or isotope. This is a constant property of the isotope and does not depend on the sample size.
There are other isotopes of hydrogen, but they are all synthetic and very unstable; their half lives are all less than 10-21 seconds, so, for practical purposes, they can be thought of as not existing except in a laboratory, and then only for an instant.
AnswerHydrogen is the smallest possible element ans therefore can only decay into particles. My guess is that Hydrogen eventually decays into individual electrons protons and neutrons via radioactive decay.%
The half life of an isotope refers to the rate at which a radioactive isotope undergoes radioactive decay. Specifically, it is the amount of time it takes for half of a given sample of a radioactive isotope to decay.
The atomic half-life of a substance - is the amount of time it takes for half the weight of a known sample to decay to an inert substance. Some radioactive elements have a relatively short half-life (less than a day). However - refined uranium has a half-life of hundreds of years !
Deuterium is stable and so does not have a half-life.
12.3 years is the half life of the isotope tritium.
The half-life of tritium is 12.32 years (12 years 3 months and 26-ish days).
The time it takes for half of the amount of a given sample of the isotope to decay.
Deuterium is stable
In ordinary water, exactly 0 atoms as Tritium decays too rapidly (halflife 12.26 years) for any that was on earth when it formed (billions of years ago) to remain. In contaminated water, either deliberately or accidentally, it would depend on how much contaminate was added and the tritium concentration in it. Tritium can only be manufactured somewhere there is a high neutron flux (e.g., nuclear reactor or bomb, a star).
How old are they? If they are about 25 years old or more they will probably be very dim and should be replaced. The halflife of Tritium is only 12.26 years, so after 25 years their brightness would be about 1/4 of what it was new. If they are less than 6 years old and not working right they are defective or broken, the tritium has probably escaped. Either way there is nothing to clean that would help. Getting a replacement Tritium ampule that fits may be difficult and/or expensive as the US has no dedicated Tritium production reactors since the shutdown of the Savanna River site in the 1990s.
Tritium. What did you think it was?
Tritium is an isotope of hydrogen, so it is colorless.
Tritium, n., A radioactive isotope of hydrogen having an atomic mass of 3.017 and a nucleus composed of 1 proton and 2 neutrons. Its halflife is 12.26 years and it decays by beta decay to Helium-3. Tritium is normally only produced synthetically on earth by placing sealed pellets of Lithium in the neutron flux of a nuclear reactor.

Tritium. What did you think it was?
The oxide of tritium is tritium oxide, sometimes called super heavy water, or 3H2O.

Tritium is not the most stable isotope known.
Tritium Dont Eat Anything? They Are Type Of Watches.... :)
Tritium decay to helium-3.
Tritium, or Hydrogen 3, has an atomic mass of 3.016.
Yes.
