Diamond and graphite are two allotropes of carbon: pure forms of the same element that differ in crystalline structure.. Allotropy or allotropism (from Ancient Greek ἄλλος (allos) 'other' and τρόπος (tropos) 'manner, form') is the property of some chemical elements to exist in two or more different forms, in the same physical state, known as allotropes of the elements.
Xenophagy (Greek "strange" + "eating") and allotrophy (Greek "other" + "nutrient") are changes in established patterns of biological consumption, by individuals or groups.. In entomology, xenophagy is a categorical change in diet, such as an herbivore becoming carnivorous, a predator becoming necrophagous, a coprophage becoming necrophagous or carnivorous, or a reversal of such changes.

Tin medal affected by tin pest. Tin pest is an autocatalytic, allotropic transformation of the element tin, which causes deterioration of tin objects at low temperatures.Tin pest has also been called tin disease, [1] tin blight, tin plague, [2] or tin leprosy. [3]

In crystallography, the transition temperature is the temperature at which a material changes from one crystal state to another. [1] More formally, it is the temperature at which two crystalline forms of a substance can co-exist in equilibrium.
Plutonium normally has six allotropes and forms a seventh (zeta, ζ) under high temperature and a limited pressure range. [2] [3] [4] These allotropes have very similar energy levels but significantly varying densities and crystal structures.
Gray, or metallic arsenic, pictured under an argon atmosphere. Gray arsenic, also called grey arsenic or metallic arsenic, is the most stable allotrope of the element at room temperature, and as such is its most common form. [1]
