Radioisotopes in radioactive dating


Other isotopes are unstable because the different number of neutrons interacts with the other atomic components in such a way that, over a period of time, the isotope changes into some other atom.

Atoms are made up of electrons, protons, and neutrons, and the number of electrons and protons determines the type of atom.When scientists date rocks from our planet this way, the oldest dates they find are 4.5 billion years.By dating the lava flows above and below a fossil find, scientists can put exact boundaries on the maximum and minimum age of that fossil.Hydrogen, for example, has one electron and one proton.
