Cold Isotope Chemistry

Isotopes react in the same way, don't they? Chemical reactions are unaffected by the isotopic composition so the percentage of different isotopes of the same element in a substance would be the same as the percentage of each naturally occurring isotope. Well, this is true on earth but it is not the case in space, deep space where the temperature is really low and the concentration of atoms very very small. In effect, one isotope will become more reactive than the other. Scientists have ...
