Tritium Atomic Number

Posted : admin On 1/2/2022

As Deuterium and Tritium are both merely isotopes of Hydrogen and not elements in their own right, they both have an atomic number of 1, just like Hydrogen (Hydrogen-1). Deuterium (Hydrogen-2) has. Tritium is the only naturally-occurring radioisotope of hydrogen. Its atomic number is naturally 1 which means there is 1 proton and 1 electron in the atomic structure. Unlike the hydrogen nucleus and deuterium nucleus, tritium has 2 neutrons in the nucleus. Thus, it is apparent that tritium exit signs, which when new may contain up to 25 curies, or 25,000,000,000,000 picocuries (pCi) of tritium, are entering landfills via municipal or residual waste streams. A single tritium emergency exit sign has the potential to cause the tritium levels observed. Tritium has an atomic mass of 3.0160492 u. Diatomic tritium (T 2 or 3 H 2) is a gas at standard temperature and pressure. Combined with oxygen, it forms a liquid called tritiated water (T 2 O). Tritium's specific activity is 9,650 curies per gram (3.57 × 10 14 Bq/g).

About 4.6 billion years ago, the solar nebula transformed into the present solar system. In order to chemically model the processes which drove that transformation, we would, ideally, like to have a sample of that original nebula to use as a baseline from which we can track changes. NASA’s Genesis sample-return mission 1 is designed to give us just such a baseline composition 2. It has collected solar wind, material which is ejected from the outer portion of the sun, and returned it to Earth. This material can be thought of as a fossil of our nebula because the preponderance of scientific evidence suggests that the outer layer of our sun has not changed measurably for billions of years. Moreover, for most rock-forming elements, there appears to be little fractionation of either elements or isotopes between the sun and the solar wind.
