  • Allotropy - Wikipedia
    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
  • What Is an Allotrope? Definition and Examples in Chemistry
    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 ”
  • Allotrope Definition and Examples: Chemistry Glossary - ThoughtCo
    The term allotrope refers to one or more forms of a chemical element that occur in the same physical state The different forms arise from the different ways atoms may be bonded together The concept of allotropes was proposed by Swedish scientist Jons Jakob Berzelius in 1841 The ability for elements to exist in this way is called allotropism
  • Allotropy | Definition, Examples, Facts | Britannica
    Allotropy, 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
  • Difference Between Allotropes and Isotopes | Definition, Properties . . .
    Allotropy is the term used to describe the presence or absence of allotropes for a particular chemical element All chemical elements do not have allotropes Only some elements show allotropy Some common examples are discussed below Carbon is a major chemical element that shows allotropy

    Allotropes are forms of a chemical element that differ at the molecular level, or in the way the atoms are arranged into molecules Many elements occur in different allotropes, among them carbon, oxygen, phosphorus, and sulfur
  • Allotropes - Chemistry Encyclopedia - structure, reaction, elements . . .
    Allotropes are different forms of the same element Different bonding arrangements between atoms result in different structures with different chemical and physical properties Allotropes occur only with certain elements, in Groups 13 through 16 in the Periodic Table This distribution of allotropic elements is illustrated in Figure 1
