The nitrogen atom, which began with seven protons and seven neutrons, is left with only six protons and eight neutrons.
As the number of protons decides the chemical nature of an atom, the atom now behaves like a carbon atom.
The tiny initial amount of C14, the relatively rapid rate of decay (the half-life of C14 is currently about 5700 years) and the ease with which samples can become contaminated make radiocarbon dating results for samples "older" than about 50,000 years effectively meaningless.When they strike ordinary atoms in the upper atmosphere, the cosmic rays smash them apart. Some of these neutrons then collide with nitrogen atoms.This collision is less destructive than the initial collision that produced them....[Some authors have said] they were "not aware of a single significant disagreement" on any sample that had been dated at different labs.Such enthusiasts continue to claim, incredible though it may seem, that "no gross discrepancies are apparent".
Radiocarbon dating has somehow avoided collapse onto its own battered foundation, and now lurches onward with feigned consistency.
