Key Points
Carbon has several allotropes, or different forms in which it can exist. These allotropes include graphite and diamond, which have very different properties.
Despite carbon’s ability to make 4 bonds and its presence in many compounds, it is highly unreactive under normal conditions.
Carbon exists in 3 main isotopes: 12C, 13C, 14C. 14C is radioactive and used in dating carbon-containing samples ( radiometric dating ).
Key Terms
allotropes: Different forms of a chemical element found in its natural state.
radiometric dating: A technique used to date materials by comparing the natural abundance of radioactive atoms to their remaining decay products.
half-life: In a radioactive decay process, the amount of time required to end up with half of the original (undecayed) material.
Explanation:
Carbon is the chemical element with the symbol C and atomic number 6 (contains 6 protons in its nucleus ). As a member of group 14 on the periodic table, it is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds. The most common isotope of carbon has 6 protons and 6 neutrons, and has an atomic mass of 12.0107 amu. Its ground state electron configuration is 1s22s22p2. Its oxidation state ranges from 4 to -4, and it has an electronegativity value of 2.55 on the Pauling scale. It is a solid, and sublimes at 3,642 °C (it has the highest sublimation point of all the elements).
