How are isotopes used to analyze things?
In: Chemistry
Iron has for stable isotopes:
* Fe-54 – 6%
* Fe-56 – 92%
* Fe-57 – 2%
* Fe-58 – trace
Iron in the earth mostly occurs in those same proportions, but not exactly. Iron from a meteorite is likely to have a different composition of isotopes than one from a mine, so be measuring these values we can tell the difference.
