The illustration below shows the three isotopes of carbon.Some isotopes of certain elements are unstable; they can spontaneously change into another kind of atom in a process called “radioactive decay.” Since this process presently happens at a known measured rate, scientists attempt to use it like a “clock” to tell how long ago a rock or fossil formed.God knows just what He meant to say, and His understanding of science is infallible, whereas ours is fallible.So we should never think it necessary to modify His Word.Scientists use a technique called radiometric dating to estimate the ages of rocks, fossils, and the earth.
Atoms are made up of much smaller particles called protons, neutrons, and electrons.Assumptions in the scientific community are extremely important.If the starting assumption is false, all the calculations based on that assumption might be correct but still give a wrong conclusion. Libby’s original work, he noted that the atmosphere did not appear to be in equilibrium. Libby since he believed the world was billions of years old and enough time had passed to achieve equilibrium. Libby’s calculations showed that if the earth started with no If the cosmic radiation has remained at its present intensity for 20,000 or 30,000 years, and if the carbon reservoir has not changed appreciably in this time, then there exists at the present time a complete balance between the rate of disintegration of radiocarbon atoms and the rate of assimilation of new radiocarbon atoms for all material in the life-cycle.2C in the atmosphere.The atomic number corresponds to the number of protons in an atom.Atomic mass is a combination of the number of protons and neutrons in the nucleus.
