ALLOTROPY

Allotropy (from the Greek allos, other and tropos, habit), is a term used to express the fact that one and the same element may exist in different forms, differing widely in external physical properties. Thus, carbon occurs as the diamond, and as charcoal and plumbago, and is therefore regarded as a substance subject to allotropy.
