In addition to diamond, there are two other well-known … WebAllotropes are elements that exist in more than one form but are in the same physical state. The Carbon the sulfur are two common chemical compound having allotropes. Due to the carbon having valence, carbon can form many allotropes. The known forms of carbon are graphite and diamond. Carbon is a non-metal with the symbol C and atomic number 6.

WebWhile uncommon, carbon can form (more-or-less) ionic bonds. The reason why ionic bonds involving carbon are rare is that carbon has an intermediate level of electronegativity, which means it is good at sharing electrons (i.e forming covalent bonds) with most other atoms.
