Isotopes of hydrogen - Wikipedia Hydrogen (1 H) has three naturally occurring isotopes: 1 H, 2 H, and 3 H 1 H and 2 H are stable, while 3 H has a half-life of 12 33(2) years [ 3 ] [ nb 1 ] Heavier isotopes also exist; all are synthetic and have a half-life of less than 1 zeptosecond (10 −21 s)
Hydrogen - Isotopes, Deuterium, Tritium | Britannica Tritium is radioactive; it has a half-life of 12 5 years, decaying to a very soft (low energy) negative beta particle (electron; the positive beta particle is called a positron) and a helium-3 nucleus
Which radioactive elements have the longest and shortest half lives . . . It has recently (2006) been found that the "stable" isotope of bismuth, element 83, isotope 209, is actually radioactive, with a half life greater than 10^19 years Bismuth is probably the best answer in terms of present knowledge and understandings
Isotopes of Hydrogen - Unacademy With a half-life of 12 32 years, tritium is the most stable radioisotope of hydrogen All heavier isotopes are created artificially and have a half-life of less than a zeptosecond (10 -21 sec) The most stable isotope is 5 H, whereas the least stable is 7 H
What is the longest radioactive halflife? - Answers For example, hydrogen-1 and hydrogen-2 are stable, while hydrogen-3 is not (half-life about 19 years) Individual atoms, in a radioactive isotope, will decay at a random moment The
Half-life period of Hydrogen (H) - Web Conversion Online Find half-life period, partical emitted, decay type for different isotopes of Hydrogen (H) or Find half-life period of radioactive isotopes of different elements; find its decay type and list of particle emitted
8. 3: Half-life of radioisotopes - Chemistry LibreTexts Natural radioactive isotopes usually have a longer half-life, e g , t 1 2 carbon-14 is 5730 years and uranium-235 is 7 0 x 10 8 years The radioisotopes used for imaging and treatment in medical sciences are usually synthesized and have a short half-life so that they may not persist in the body for an unnecessarily long time
Hydrogen - Simple English Wikipedia, the free encyclopedia Hydrogen has 7 known isotopes, two of which are stable (1 H and 2 H), which are commonly named protium and deuterium The isotope 3 H is known as tritium, has a half-life of 12 33 years, and is produced in small amounts by cosmic rays The 4 isotopes left have half-lives on the scale of yoctoseconds Hydrogen in nature In its natural form on Earth, hydrogen is generally a gas Hydrogen is also
