Dendrochronology and radiocarbon dating
Only two of the carbon isotopes are stable (C is obviously much more common (99%).
The fact that it has seven protons is what makes it nitrogen.
To understand this process we must first understand a little bit about the atoms themselves and how they get their names.
Most carbon atoms have six positively charged protons and six uncharged neutrons.
Carbon-14 dating techniques were first developed by the American chemist, Willard F.
Libby at the University of Chicago in the 50’s, for which he received the Nobel Prize in Chemistry in 1960.
Also you will see that the Mass and Atomic Numbers in the equation are equal on both sides of the equation.
