From Wikipedia, the free encyclopedia
Carbon[1] es un elemento chimic de symbolo C e numero atomic 6. Dependente del conditiones de su formation, carbon pote trovar se in le natura in le forma de carbon amorphe, graphite o diamante. In decennios recente, altere allotropos ha essite discoperite: graphene, nanotubos, e varie fullerenes.
