Carbon a streak on paper (hence its name, from the Greek verb "γράφειν" which means "to write"), while diamond is the hardest naturally occurring material known. Graphite is a good electrical conductor while diamond has a low electrical conductivity. Under normal conditions, diamond, carbon nanotubes, and graphene have the highest thermal conductivities of all known materials. All carbon allotropes are solids under normal conditions, with graphite being the most thermodynamically stable form at standard temperature and pressure. They are chemically resistant and require high temperature to react even with oxygen. The most common oxidation state of carbon in inorganic compounds is
Inside the Atom did not have adequate science reading material. Inside the Atom Inside the Atom is a popular science book by American author Isaac Asimov. The first edition of the book was published in 1956 by Abelard-Schuman. Revised editions were brought out in subsequent years. The book describes the internal structure of the atom. The sequence of concepts described in the book follows the sequence that those facts were discovered in. It describes the various sub-atomic structures within the atom, and the functions they fill in the whole structure. Later chapters describe chemical elements and isotopes, the stability and instability of atomic
