Whether these life forms take in carbon to help manufacture food or release carbon as part of respiration, the intake and output of carbon is a … WebThe number of protons in a nucleus determines the element’s atomic number on the Periodic Table. For example, carbon has six protons and is atomic number 6. Carbon occurs naturally in three isotopes: carbon 12, which has 6 neutrons (plus 6 protons equals 12), carbon 13, which has 7 neutrons, and carbon 14, which has 8 neutrons.

WebIf you really want pure carbon-12 I guess there is no other way than separating out the carbon-14. This is no easy task but is possible, see for instance this wiki page on isotope separation. Maybe you can buy some sort of carbon-product for chemistry research use which already is free from carbon-14 and use that as a starting point. WebIt is possible to determine the probability that a single atomic nucleus will "survive" during a given interval. This probability amounts to 50% for one half-life. In an interval twice as long (2 T) the nucleus survives only with a 25% probability (half of 50%), in an interval of three half-life periods (3 T) only with 12.5% (half of 25%), and ... how does bone grow in length
