The half-life of hydrogen-3 (tritium) is approximately 12 years. In how many years will half of a 20-gram sample decay by beta radiation to helium-3

12
For this the easiest way to work this out is to think of the amount of decay as a percentage. so in 12 years its down to 50% another 12 years its down to 25%, another 12 years its 11.5 %. 

For a 20 gram sample to decay by half will still be 12 years no matter how many grams one has.

Hydrogen-3, or tritium, is an uncommon, radioactive isotope of hydrogen. It is comprised of a core of one proton and two neutrons.


The mellow radiation discharged by tritium makes the substance helpful in commercial, military, and logical undertakings. Additionally, it is moderately protected, as the radiation it emanates can't enter the human skin.
