Allotropy - Wikipedia
WEBAllotropy 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.

Allotropy | Definition, Examples, & Facts | Britannica
WEBAllotropy, the existence of a chemical element in two or more forms, which may differ in the arrangement of atoms in crystalline solids or in the occurrence of molecules that contain different numbers of atoms. Elements exhibiting allotropy include tin, carbon, sulfur, phosphorus, and oxygen.
Allotropy - Oxford Reference
WEBQuick Reference. The existence of elements in two or more different forms (allotropes). In the case of oxygen, there are two forms: ‘normal’ dioxygen (O 2) and ozone, or trioxygen (O 3 ). These two allotropes have different molecular configurations. More commonly, allotropy occurs because of different crystal structures in the solid, and is ...
What Is an Allotrope? Definition and Examples in Chemistry
WEBAug 3, 2020 · Allotropes are defined as different structural forms of a single chemical element. These forms result from the different ways atoms can bond to one another. Swedish chemist Jöns Jakob Berzelius proposed the concept of allotropy in 1841. The word “allotropy” comes from the Greek word allotropia, which means “changeableness.”
Allotropy - Simple English Wikipedia, the free encyclopedia
WEBAllotropy (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. This happens when the atoms of the element are bonded together in a different way.

Allotropy | SpringerLink
WEBAllotropy (so named by J. J. Berzelius in 1841) refers to the existence of a chemical element in two or more distinct forms having different crystalline structures and/or physical properties. Allotropes may differ with respect to density, melting point, molar volume, color, and other physical properties.
