Half Life for all the elements in the Periodic Table

WebCarbon occurs naturally in three isotopes: carbon 12, which has 6 neutrons (plus 6 protons equals 12), carbon 13, which has 7 neutrons, and carbon 14, which has 8 neutrons. Every element has its own number of isotopes. ... WebDec 30, 2024 · The isotopes carbon-12 and carbon-13 are stable, but carbon-14 is radioactive. It decays into nitrogen-14 ( 14 N) through beta decay. The half-life of carbon-14 is about 5,730 years , which means that after 5,730 years, half of the original amount of carbon-14 will have decayed into nitrogen-14. WebThis stable sixth element on the periodic table contains three diverse isotopic forms—carbon 13, carbon-13, and carbon-14. Each is found naturally on Earth, but only one is uniquely unstable. The most generally-recognizable isotope is carbon-14 due to its radioactivity, with a notable half-life of 5,730 years. asxianajotoimistot
