Ninety-nine percent of these also contain six neutrons.

The 6 proton 6 neutron atoms are said to have a mass of 12 and are referred to as "carbon-12." The nuclei of the remaining one percent of carbon atoms contain not six but either seven or eight neutrons in addition to the standard six protons.

Along with hydrogen, nitrogen, oxygen, phosphorus, and sulfur, carbon is a building block of biochemical molecules ranging from fats, proteins, and carbohydrates to active substances such as hormones.

All carbon atoms have a nucleus containing six protons.

Carbon-14 is most abundant in atmospheric carbon dioxide because it is constantly being produced by collisions between nitrogen atoms and cosmic rays at the upper limits of the atmosphere.

This does not mean that recalibration is bad, indeed it is necessary, but it should make one more soberly assess any reported dates as being tentative.

The problem is that most people reporting on these issues fail to report the initial number along with the calibrated date. The Jericho controversy is soundly rooted in C-14 calibration.

Additional tests were done on six grain samples from the destruction level resulting in dates between 16 B. and 12 charcoal samples from the destruction level resulting in dates between 16 B. The literature on the subject is enormous, so I will not attempt to give you references.

There is a heated debate going on among scholars concerning this, especially with regard to the date of the eruption of Thera (Santorini).Radiocarbon, or carbon 14, is an isotope of the element carbon that is unstable and weakly radioactive. Carbon 14 is continually being formed in the upper atmosphere by the effect of cosmic ray neutrons on nitrogen 14 atoms.
