(2) Absolute dating method provide an approximate date in year. (3) Carbon is one of the chemical element on the Earth. (4) All carbon atom have a nucleus containing six protons and 99% of these also countoin six neutrons.     6 Proton + 6 Neutron = Carbon 12 (5) C12 and C13 are stable, but C14 is not. (6) In any given mass of C-14, half of them will decay in 5730 years. ■ Dating techniques are procedures us...
