Carbon-12 has an atomic weight of 12, which is made up of 6 protons and 6 neutrons.
Understand how decay and half life work to enable radiometric dating.
In addition, Carbon-12 and Carbon-13 forms are stable—that is to say, they don’t change over time.
Carbon-14, on the other hand, is not stable but instead decays at a known rate—because of that, we can use its remaining ratio to Carbon-13 to calculate radiocarbon dates, but that’s another issue entirely. During the process of photosynthesis, plants absorb the carbon atoms in earth’s atmosphere, water, and soil, and store them in the cells of their leaves, fruits, nuts, and roots.
The researchers first looked at the descriptions of the users.
Fiore and colleagues analyzed the dating profiles with a software tool known as the Linguistic Inquiry and Word Count (LIWC) (Pennebaker, Francis and Booth, 2001).
