Ode to the Chemical Element Carbon

摘要: If an element deserves praise, then this is carbon. Its nucleus, along with N and O, catalyzes the fusion of H into He in sun sun-like stars. minor stable isotope allows chemical structure to be elucidated by 13C-NMR, 1H-NMR. long-lived radioisotope 14C radiocarbon dating, reaction mechanisms or bioactivities medicines understood isotopic labeling. short-lived 11C used for PET scans. The 16th part its atomic weight serves as unified mass unit, also called “dalton”. allotropes (diamond, graphite, fullerenes) have extremely useful properties. And above all: it that life based upon, central organic chemistry, present most 7 × 107 substances registered till now. Due fact multiple uses carbon compounds, although now known they do not differ from inorganic Organic Chemistry still a distinct chemistry. Because atoms form molecules covalent bonds can represented hydrogen-depleted molecular graphs, makes search best scientific documentation among all sciences. Substantial consideration dedicated derived hydrocarbon fragments such diamondoids benzenoids, emphasizing author’s theoretical contributions these research fields.
