Dating with carbon 14 www theonlinedatingguide com
Looking specifically at Carbon-14, we see that it is a Beta emitter with a half life of 5730 years.When Carbon-14 emits a beta particle, the Carbon-14 atom becomes a Nitrogen-14 Atom.Looking at the Mass Number and Atomic Number of the atoms we see that the atom has lost a neutron and gained a proton.Also you will see that the Mass and Atomic Numbers in the equation are equal on both sides of the equation.

Most carbon atoms have six positively charged protons and six uncharged neutrons.
Since protons and neutrons weigh about the same, the atomic mass of ordinary carbon is 6 6 = 12.
It is called "Carbon-12," which is abbreviated "C." The fact that the atom has six protons is what makes it carbon.
Most nitrogen atoms have seven protons and seven neutrons, so their atomic mass is 7 7 = 14.
