"How can creationists expect people to accept a young earth when science has proved through radiometric dating that the earth is billions of years old?

" This article addresses that question, which represents the thinking of a large number of people today.

The excess energy associated with this excited state is released when the nucleus emits a photon in the -ray portion of the electromagnetic spectrum.

Most of the time, the -ray is emitted within 10Nuclides with atomic numbers of 90 or more undergo a form of radioactive decay known as spontaneous fission in which the parent nucleus splits into a pair of smaller nuclei.

We know these steps because researchers followed the progress of the radioactive carbon-14 throughout the process.

Radioactive isotopes are useful for establishing the ages of various objects.

One is the Carbon-14 system used for dating fragments of once-living organisms.

It's never used for non-organic samples, and almost never even attempted if the sample is thought to be much older than about 50,000 years.

Since Nitrogen gas makes up about 78 percent of the Earth's air, by volume, a considerable amount of Carbon-14 is produced.

Radioactive isotopes have a variety of applications.

Generally, however, they are useful either because we can detect their radioactivity or we can use the energy they release.

As you learned in the previous page, carbon dating uses the half-life of Carbon-14 to find the approximate age of certain objects that are 40,000 years old or younger.

In the following section we are going to go more in-depth about carbon dating in order to help you get a better understanding of how it works.

Alpha decay of the The sum of the mass numbers of the products (234 4) is equal to the mass number of the parent nuclide (238), and the sum of the charges on the products (90 2) is equal to the charge on the parent nuclide.
