The half-life of a radioactive element is the time that it takes for one half of the atoms of that substance to disintegrate into another nuclear form. These can range from mere fractions of a second, to many billions of years. In addition, the half-life of a particular radionuclide is...
The normal carbon is carbon-12. C-14 has two more neutrons with a half-life of 5730 years. The process by which scientists use carbon 14 is called carbon dating. The carbon dating method is very old when scientists try to measure the age of matter. Half of life is independent of ...
