what can you tell about its electrical conductivity properties?
Blue diamonds are natural semiconductors, in contrast to most diamonds, which are excellent electrical insulators.

describe carbon in covalent bonds and the importance of it It is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds what are the characteristics of this element? Carbon is the sixth element, with a ground-state electron configuration of 1s2s2p, of which the four outer electrons are valence electrons. Its first four ionisation energies, 1086.5, 2352.6, 4620.5 and 6222.7 kJ/mol, are much higher than those of the heavier group-14 elements. where this element can be found in the earth? Earth's crust what are its most common allotropes? Amorphous carbon, graphite, and diamond how did this element get its name? The English name "carbon" comes from the Latin "carbo" for coal and charcoal, whence also comes the French "charbon", meaning charcoal. what is the last allotrope? Diamond is a solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic.

Diamond [SEP] Electrical conductivity
Other specialized applications also exist or are being developed, including use as semiconductors: some blue diamonds are natural semiconductors, in contrast to most diamonds, which are excellent electrical insulators. The conductivity and blue color originate from boron impurity. Boron substitutes for carbon atoms in the diamond lattice, donating a hole into the valence band. Substantial conductivity is commonly observed in nominally undoped diamond grown by chemical vapor deposition. This conductivity is associated with hydrogen-related species adsorbed at the surface, and it can be removed by annealing or other surface treatments. A 2020 paper reported that extremely thin needles of diamond can be made to vary their electrical resistance from the normal (5.6 eV bandgap) to near zero by selective tensile deformation.
