One rare form has atoms that are 14 times as heavy as hydrogen atoms: carbon-14, or C ratio gets smaller.
The isotopes of a particular element have virtually identical chemical properties.
C) dating usually want to know about the radiometric dating methods that are claimed to give millions and billions of years—carbon dating can only give thousands of years.
Isotopes can thus be ‘tagged’ (using suitable detection devices such as geiger counters and autoradiography) as biochemical processes occur. An unstable form of an element that gives off radiation to become stable.
Elements are characterized by the number of electrons around each atom.
The rate of decay of N in 5,730 years (plus or minus 40 years).
This is the “half-life.” So, in two half-lives, or 11,460 years, only one-quarter of that in living organisms at present, then it has a theoretical age of 11,460 years.
Obviously, this works only for things which were once living.
It cannot be used to date volcanic rocks, for example.
Carbon has unique properties that are essential for life on Earth.
Familiar to us as the black substance in charred wood, as diamonds, and the graphite in “lead” pencils, carbon comes in several forms, or isotopes.
