Do allotropes have the same configuration (grouping) of their atoms? Diamonds are a colorless, crystalline solid where each carbon atom is bonded to four others in a network pattern. Allotropes are forms of the same element which exhibit different physical properties. Allotropes of carbon: The phenomenon of existence of allotropic forms of an element is called allotropy.Allotropes are the different forms of the same element having different physical properties but almost similar chemical properties due to different arrangements of atoms.There are three allotropes of carbon these are diamond, graphite and fullerene. 3) Fullerenes. ; Graphene – is the basic structural element of other allotropes, nanotubes, charcoal, and fullerenes. Allotropes are variations in the forms of an element which differ in molecular composition or the way in which atoms form different packing arrangements in the solid state. Carbon can form Pπ-Pπ multiple bonds with itself and other atoms having small size and high electronegativity. The presence of one element in various structures, having distinctive physical properties, however comparable chemical properties are known as Allotropy.Diverse types of an element are called "Allotropes" or Allotropic Structures.Carbon demonstrates allotropy. The order of catenation is C >> Si > Ge ≈ Sn. Lonsdaleite – also called hexagonal diamond. • In Fact there are 8 different allotropesIn Fact, there are 8 different allotropes The physical properties of carbon vary widely with the allotropic form.
