Carbon is one of the most stable elements known to man.Historically, the sword developed in the Bronze Age, evolving from the dagger; the earliest specimens date to about 1600 BC.The later Iron Age sword remained fairly short and without a crossguard.This tendency to decay, called radioactivity, is what gives radiocarbon the name radiocarbon.The atmosphere contains many stable carbon atoms and relatively few radiocarbon atoms.
