Daughter Isotopes and Half-Life The half-life of an isotope is used to predict the time half of a sample will decay into a daughter isotope, but it cannot predict when an individual atom will decay into a daughter product. However, the nature of the decay product(s) form is highly predi...
For the purposes of the scope of this book this definition is enough even if, as seen in Chapter 2, the world is far more complex than that. Although this is a simplification most observable patters of nuclear chemistry can be explained and the nomenclature can be kept simple. For example...

(1D) from CO photolysis to avoid photoionization and exchange of C+with CO, which erases the isotope self-shielding isotope signature in the liberated carbon atoms. The chemistry of molecular carbon is quite complex in the solar nebula, and the fate of CH must be evaluated in a complete ...

The localized calcite precipitation- inducing effect on carbonate chemistry may even allow coccoliths to be built in a mostly calcite under-saturated vesicle. Little work has been undertaken to understand the localized influences of polysaccharides on carbonate chemistry however. Under the modelled range ...
