This means that although they are very similar chemically, they have different masses.The total mass of the isotope is indicated by the numerical superscript.Kieth and Anderson show considerable evidence that the mussels acquired much of their carbon from the limestone of the waters they lived in and from some very old humus as well.The technique of comparing the abundance ratio of a radioactive isotope to a reference isotope to determine the age of a material is called radioactive dating.This article will answer several of the most common creationist attacks on carbon-14 dating, using the question-answer format that has proved so useful to lecturers and debaters. Answer: Cosmic rays in the upper atmosphere are constantly converting the isotope nitrogen-14 (N-14) into carbon-14 (C-14 or radiocarbon).Living organisms are constantly incorporating this C-14 into their bodies along with other carbon isotopes.

C) dating usually want to know about the radiometric[1] dating methods that are claimed to give millions and billions of years—carbon dating can only give thousands of years.

Radiocarbon dating works by comparing the three different isotopes of carbon.

Isotopes of a particular element have the same number of protons in their nucleus, but different numbers of neutrons.

The Stable Isotope Laboratory offers the possibility to analyse the composition of stable isotopes in carbonates (C in dissolved inorganic carbon).

Due to the fact that during physicochemical processes like evaporation the composition of stable isotopes changes, their composition can be used to reconstruct these processes or the environmental conditions in general.
