Radiometric dating methods science

Radiometric dating methods are the strongest direct evidence that geologists have for the age of the Earth.

All these methods point to Earth being very, very old -- several billions of years old.

Uraniums abbreviation is U, so uranium-238 can be more briefly written as U238.

Many nuclides are stable -- they will always remain as they are unless some external force changes them.

After emission, it quickly picks up two electrons to balance the two protons, and becomes an electrically neutral helium-4 (He4) atom. When an atom emits a beta particle, a neutron inside the nucleus is transformed to a proton.

The mass number doesn't change, but the atomic number goes up by 1.

When I first became interested in the creation-evolution debate, in late 1994, I looked around for sources that clearly and simply explained what radiometric dating is and why young-Earth creationists are driven to discredit it.The new atom doesnt form the same kinds of chemical bonds that the old one did. It may not even be able to hold the parent atoms place in the compound it finds itself in, which results in an immediate breaking of the chemical bonds that hold the atom to the others in the mineral. In the next part of this article, Ill examine several different radiometric dating techniques, and show how the axioms I cited above translate into useful age measurements. C14 is also formed continuously from N14 (nitrogen-14) in the upper reaches of the atmosphere.And since carbon is an essential element in living organisms, C14 appears in all terrestrial ( get C14 from the environment.In alpha decay, the radioactive atom emits an alpha particle.An alpha particle contains two protons and two neutrons.
