Allotropy is the property of some chemical elements to exist in two or more different forms, or allotropes, when found in nature. • In Fact there are 8 different allotropesIn Fact, there are 8 different allotropes This bonding structure makes diamond the hardest material known. The interesting characteristic of carbon is its ability to form many For example, diamond is highly transparent, but graphite is opaque and black. 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. The highest grade, anthracite, is about 90% carbon and 10% other elements. Lonsdaleite – also called hexagonal diamond.
