Short video description
Radioactive decay[ edit ] Example of a radioactive decay chain from lead Pb to lead Pb. The final decay product, lead Pb , is stable and can no longer undergo spontaneous radioactive decay. All ordinary matter is made up of combinations of chemical elements , each with its own atomic number , indicating the number of protons in the atomic nucleus. Additionally, elements may exist in different isotopes , with each isotope of an element differing in the number of neutrons in the nucleus.

Gillaspy has taught health science at University of Phoenix and Ashford University and has a degree from Palmer College of Chiropractic. Radiometric dating is used to estimate the age of rocks and other objects based on the fixed decay rate of radioactive isotopes. Learn about half-life and how it is used in different dating methods, such as uranium-lead dating and radiocarbon dating, in this video lesson. Radiometric Dating The aging process in human beings is easy to see. As we age, our hair turns gray, our skin wrinkles and our gait slows.

Radiometric Dating: Methods, Uses & the Significance of Half-Life

Unlike the radioactive isotopes discussed above, these isotopes are constantly being replenished in small amounts in one of two ways. The bottom two entries, uranium and thorium, are replenished as the long-lived uranium atoms decay. These will be discussed in the next section. The other three, Carbon, beryllium, and chlorine are produced by cosmic rays--high energy particles and photons in space--as they hit the Earth's upper atmosphere. Very small amounts of each of these isotopes are present in the air we breathe and the water we drink.

A major assumption underlying all radioactive dating techniques is that decay rates, which have been essentially constant over the past years, have also been constant over the past 4,,, years. This is a huge and critical assumption that few have questioned. There are a number of evidences which show that radioactive decay rates were once much faster than they are today. For example, scientists have observed dormant or viable bacteria in fossils which are presumably dated to tens or hundreds of millions of years old yet there is no known metabolic process which could account for this. Metabolic rates do not drop to zero in dormancy.

    In a world were even the most earnest attempt at friendliness or kindness can and often does offend someone some where and if I were to blindly accept your God is real then you are asking the wrong question.
