Indium tin oxide (ITO)-free optoelectronic devices have been discussed for a number of years in the light of a possible indium shortage as demand rises. Chemical Reactivity of Carbon Carbon compounds form the basis of all known life on Earth, and the carbon-nitrogen cycle provides some energy produced by the sun and other stars. Do allotropes have the same configuration (grouping) of their atoms? Carbon can form Pπ-Pπ multiple bonds with itself and other atoms having small size and high electronegativity. 14. It can also be prepared artificially but because of the high cost and poor quality, diamonds are seldom made artifically.
