Elements are classified by the number of protons in the nucleus of the atom. However, there is no set rule for how many neutrons can be in the atom's nucleus. Because this number can vary, we classify the different, naturally occurring, variations of neutron quantities as isotopes of the ...
Most people are familiar with carbon dating, which uses the decay of the radioactive carbon-14 isotope to find the ages of things that were once alive. Carbon-14’s half-life is about 5730 years and the technique is not useful for material more than about 60 thousand years old. Potassium...

Potassium ordinarily has 19 protons and 21 neutrons, giving it about the same atomic mass as argon (just under 40) but with a different composition of protons and neutrons. When a radioactive particle known as a beta-particle collides with potassium, it can convert one of the protons in the...
