The half-life of C 14 is years. C 12 and C 14 are isotopes of the carbon atom. Furthermore, since both C 12 and C 14 have the same number of protons, their atomic number is the same, but their atomic weights are different because of the different number of neutrons. So, this is a significant difference between C 12 and C Moreover, C 12 and C 14 also behave differently when it comes to nuclear reactions.
Besides, C 12 is a stable isotope of Carbon while C 14 is an unstable isotope of the Carbon atom and undergoes radioactive decay. Carbon atom always has 6 protons, but the number of neutrons can vary. For example, carbon 12 and carbon 14 are different isotopes of carbon having different numbers of neutrons.
Hence, the key difference between carbon 12 and carbon 14 is that carbon 12 has 6 neutrons in its atomic nucleus whereas carbon 14 has 8 neutrons. With a mind rooted firmly to basic principals of chemistry and passion for ever evolving field of industrial chemistry, she is keenly interested to be a true companion for those who seek knowledge in the subject of chemistry.

Carbon 12 contains a larger portion of living organisms when compared to Carbon 14 Martin Kamen and Sam Ruben are credited with the discovery of Carbon 14 in Summary 1. Author Recent Posts.

In other words, the number of protons is what gives each element its unique, individual identity.
For example, a carbon atom has six protons, but an atom with only five protons is boron while an atom with seven protons is the element nitrogen. Neutrons are neutral - they have no charge. Isotopes are atoms of the same element that have a different number of neutrons. Although isotopes of the same element are twins when it comes to reactivity, the different number of neutrons means that they have a different mass.
NOAA atmospheric scientists use these isotopic labels to determine what percent of that carbon was derived from fossil fuels, the terrestrial biosphere, or from the ocean.
Carbon isotopes come in three forms. By far the most common isotope of carbon is carbon 12 C , which contains six neutrons in addition to its six protons.
