Principles of radiometric dating
Uranium-238 contains 92 protons and 146 neutrons, while uranium-235 contains 92 protons and 143 neutrons.To keep it short, a nuclide is usually written using the elements abbreviation.In alpha decay, the radioactive atom emits an alpha particle.An alpha particle contains two protons and two neutrons.Author by : Mike Walker Languange Used : en Release Date : 2013-04-30 Publisher by : John Wiley & Sons Description : This introductory textbook introduces the basics of dating, the range of techniques available and the strengths and limitations of each of the principal methods.

To explain those rules, I'll need to talk about some basic atomic physics. Hydrogen-1's nucleus consists of only a single proton.

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.
