An abundant nonmetallic, tetravalent element, carbon has several allotropic forms. 1) CARBON-12(12C) ---> it has six neutrons and six protons. It produces products which are carbon monoxide or carbon and water. With the exception of hydrogen, the most abundant isotopes of the natural elements have the same number of protons and neutrons. The electron arrangement is the same owing to same chemical properties. They are safe and inert. Saturated compounds undergo complete combustion. Mass number determines the physical properties such as boiling/melting/density etc. Another property is the atomic mass of the element, which is the sum of protons and neutrons in the nucleus or its total mass. Carbon-14, which is radioactive, is the isotope used in radiocarbon dating and radiolabeling. A knowledge of the half life of C14, along with the current ratio of C12 to C14, helps determine the age. Isotopes of carbon are extensively used for radiocarbon dating (carbon-14), molecular structure and medical research (carbon-13). C-14 is created in the upper altitudes of the atmosphere from 14N (Nitrogen-14), through the bombardment of cosmic neutrons (about 9 to 15 km above the Earth’s surface) and marginally through other terrestrial sources. The shortest-lived isotope is Carbon-8, with a half life of 2.0 x 10-21 seconds. A… Carbon. However they have different numbers of neutrons, which affects the mass number. The atomic constitution of three isotopes of hydrogen are illustrated: Carbon-14, which has a half-life of 5,730 years, is a naturally occurring isotope that can also be produced in a nuclear reactor. Out of the 15, 13 are radioactive isotopes. The physical properties of carbon vary widely with the allotropic form. Though the element has as many as 15 isotopes, only three are naturally occurring, while the rest are artificially transmuted elements, ephemeral in nature, lasting from a few nanoseconds to a few minutes. Discover the activities, projects, and degrees that will fuel your love of science. Some examples of isotopes include the isotopes of Hydrogen, Helium, Carbon, Lithium, etc. There are 15 known isotopes of carbon. They also create active derivatives. C, is most abundant on Earth, constituting about 98.89% of the atoms in one mole of carbon, C, The longest-lived among the radioactive isotopes is carbon-14, with a half-life of 5700 years. Carbon (6 C) has 15 known isotopes, from 8 C to 22 C, of which 12 C and 13 C are stable.The longest-lived radioisotope is 14 C, with a half-life of 5,730 years.

It is a solid, and sublimes at 3,642 °C (it has the highest sublimation point of all the elements). These isotopes have the same number of protons but a different number of neutrons wherein protium has zero, deuterium has one and tritium … The element forms millions of compounds, that orchestrate the functioning of organic life on our planet. C13 has applications in NMR (Nuclear Magnetic Resonance), as it has a nuclear spin, which can respond to a radio frequency signal (as opposed to C12 which hasn’t). Though they all have the same number of protons (6), each one differs in the number of neutrons, in the nucleus. Graphite is the most ther… A radioactive isotope of carbon, carbon-14, can be used to figure out how old some objects are or when something died. They have similar chemical properties because isotopes of an element have the same number of electrons as an atom of that element. These cookies do not store any personal information. See also. It occurs in the same physical state in two or more crystalline forms. Some carbon isotopes have 7 or 8 neutrons.
