Explore: Allotropy

Allotropy or allotropism (from Ancient Greek ἄλλος (allos) 'other' and τρόπος (tropos) 'manner, form') is the property of some chemical elements to exist

polycrystals. For pure chemical elements, polymorphism is referred to as allotropy. For example, diamond and graphite are two crystalline forms of carbon

ability of an element to exist in one of many structural forms is known as 'allotropy'. The reference state of an element is defined by convention, usually
