Scientists can determine the exact age of a fossil by a technique called Radiometric dating. Radiocarbon dating involves the determination of how much carbon is left in the fossil.
In radiocarbon dating, it is possible to determine how much carbon is left in the fossil, by looking at its half-life period.
Radiocarbon dating (also known as carbon dating) refers to the technique aimed at determining the age of a fossil by exploring the properties of a radioactive carbon isotope called radiocarbon.
Radiocarbon or carbon-14 (14C) is a radioactive carbon isotope of carbon that contains 6 protons and 8 neutrons, whose amount in a sample can de be used to determine the age of a given organic material.
