The difference is the number of neutrons. Explanation: Carbon 12, 13 and 14 are carbon isotopes, meaning that they have additional neutrons: Carbon 12 has exactly 6 protons and 6 neutrons hence the 12 Carbon 13 has 6 protons and 7 neutrons Carbon 14 has 6 protons and 8 neutrons Because molecular mass is calculated by adding the number of protons and neutrons, you could also say that the difference between these isotopes is mass if you have 1 mole of each isotope, carbon 14 would have the greatest mass.
Carbon 14 is also radioactive with a half-life of years. Related questions What are the two sources for atmospheric CO2? How is nitrogen drawn out from the atmosphere? Carbon has 6 protons, just like other carbon isotopes, but it has 7 neutrons. It is not radioactive. Although 15 isotopes of carbon are known, the natural form of the element consists of a mixture of only three of them: carbon, carbon, and carbon Most of the atoms are carbon Measuring the difference in the ratio between carbon and carbon is useful for dating the age of organic matter since a living organism is exchanging carbon and maintaining a certain ratio of isotopes.
In a diseased organism, there is no exchange of carbon, but the carbon that is present undergoes radioactive decay, so over time the change in isotope ratio becomes greater and greater.

But you may not realise that each square on the periodic table actually represents a family of isotopes — atoms which share the same name and chemical properties, but have different masses.
To understand what isotopes are and how we can use them, we need to take a closer look at the interior of an atom. An atom is composed of an incredibly dense core called a nucleus of protons and neutrons , surrounded by a diffuse cloud of electrons. You can think of protons and neutrons as the same kind of particle with one key difference: the protons are positively charged, while neutrons carry no charge. The electrons, which are much lighter than protons or neutrons, carry the same magnitude of charge as a proton but with the opposite sign, meaning that each atom that has equal numbers of protons and electrons is electrically neutral.
Isotopes of an element share the same number of protons but have different numbers of neutrons. There are three isotopes of carbon found in nature — carbon, carbon, and carbon All three have six protons, but their neutron numbers - 6, 7, and 8, respectively - all differ. Chemically, all three are indistinguishable, because the number of electrons in each of these three isotopes is the same. So different isotopes of the same element are identical, chemically speaking. But some isotopes have the ability to circumvent this rule by transforming into another element entirely.
This transformative ability some isotopes have has to do with the fact not all isotopes are stable, and is what led Frederick Soddy to his Nobel Prize-winning discovery of isotopes in Some isotopes - such as carbon - will happily continue to exist as carbon unless something extraordinary happens.
Others - carbon, say - will at some point decay into a stable isotope nearby. In this case, one of the neutrons in carbon changes into a proton, forming nitrogen During this process, which is known as beta decay , the nucleus emits radiation in the form of an electron and an antineutrino.
There are many factors that can cause a nucleus to decay.
