Radioactive dating for kids

Many secular scientists use it to dismantle the faith of Christians and cause them to accept uniformitarian assumptions that, in addition to being scientifically erroneous, demand a figurative and distorted interpretation of Genesis.Being knowledgeable about such a widespread dating method is essential for Christians to address opposing arguments and critics. Natural radioactivity was discovered in 1896 by the French physicist Henri Becquerel.When an organism, eg a tree, dies it stops taking in carbon dioxide.The amount of carbon-14 in the wood decreases with time as it decays into nitrogen with a half-life of about 5700 years.The protons and neutrons form the nucleus of an atom with approximate diameters ranging from 1.75 fm for the hydrogen atom to 15 fm for the uranium atom.The chemical properties of each element are defined by the number of protons it contains in its nucleus and, consequently, the number of corresponding electrons that orbit it.Because these families have the same number of protons in the nucleus, they also have the same number of electrons orbiting the nucleus and thus exhibit the same chemical behavior.It is the differing number of neutrons that give rise to stable and unstable isotopes (radioisotopes) within a given elemental family.

Many of us believed that string theory was a very dramatic break with our previous notions of quantum theory.

Before we delve into radioactive decay and its use in dating rocks, let’s review some essential nuclear physics concepts.

Each atom is made up of protons and neutrons concentrated in the atom’s center—its nucleus—around which electrons orbit.

The age of the rock can be calculated if the ratio of uranium to lead is known.

As the rock gets older the proportion of lead increases.


  1. Radioactive Decay Worksheet. Radiometric Dating Worksheet When radioactive isotopes. the radioactive isotopes that they do contain have half-lives that.

  2. Radioactive dating is a method of dating rocks and minerals using radioactive isotopes. This method is useful for igneous and metamorphic rocks, which cannot be

  3. Radioactive Dating. Because the radioactive half-life of a given radioisotope is not affected by temperature, physical or chemical state, or any other influence of.

  4. More radioactive dating - higher tier only Carbon dating. The amount of carbon-14 in the atmosphere has not changed in thousands of years. Even though it decays into.

  5. Radiometric dating using the naturally-occurring radioactive elements is simple in concept even though technically complex. If we know the number of radioactive.
