Allotropy - Simple English Wikipedia, the free encyclopedia

Allotropy (or allotropism) is when a chemical element can exist in two or more different forms in the same physical state or phase.These different forms are called allotropes.Therefore, an allotrope is a different structure in which an element appears.
