Carbon-11 or 11 C is a radioactive isotope of carbon that decays to boron-11. This decay mainly occurs due to positron emission, with around 0.19–0.23% of decays instead occurring by electron capture. [6] [7] It has a half-life of 20.3402(53) min. 11 C → 11 B + e + + ν e + 0.96 MeV 11 C + e − → 11 B + ν e + 1.98 MeV
3 kwi 2019 · This can easily be understood by considering that the ratio between the total mass of a 11 C-labeled precursor (carbon-12 and carbon-11) and the precursor for labeling typically is in the order of 1/100.
This table lists the mass and percent natural abundance for the stable nuclides. The mass of the longest lived isotope is given for elements without a stable nuclide.
The half-life calculator is a tool that helps you understand the principles of radioactive decay. You can use it to not only learn how to calculate half-life, but also as a way of finding the initial and final quantity of a substance or its decay constant.
13 cze 2023 · We can determine the amount of a radioactive isotope remaining after a given number half-lives by using the following expression: \[amount\; \: remaining\: =\: initial\:amount\times \left ( \frac{1}{2} \right )^{n} \nonumber \]
