What is the simple definition of allotrope?
allotrope. / (ˈæləˌtrəʊp) / noun. any of two or more physical forms in which an element can existdiamond and graphite are allotropes of carbon.
What is the best definition of an allotrope?
Allotrope meaning Any of several crystalline forms of a chemical element. Charcoal, graphite, and diamond are all allotropes of carbon. A chemical element that can take on different forms based on the structure of, or the number of atoms in, the molecule. Note: Different structural forms of a compound are isomers.
What does allotrope mean in chemistry?
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.
What are the three types of allotropes?
Diamond, graphite and fullerenes (substances that include nanotubes and ‘buckyballs’ , such as buckminsterfullerene) are three allotropes of pure carbon.
What is called as the allotrope?
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 allotrope give example?
The term allotrope refers to one or more forms of a chemical element that occur in the same physical state. For example, graphite and diamond are both allotropes of carbon that occur in the solid state. Graphite is soft, while diamond is extremely hard.
What is an allotrope Class 10?
Answer: The term allotrope refers to one or more physical forms of a chemical element that occurs in the same physical state. Allotropes may show differences in chemical and physical properties.
What are the 4 allotropes of carbon?
Use the accompanying fact sheet and differentiated flash card activity to explore the different properties and uses of four allotropes of carbon – diamond, graphite, graphene and buckminsterfullerene.
What are the 5 allotropes of carbon?
Allotropes of Carbon: Allotropes of carbon: a) Diamond, b) Graphite, c) Lonsdaleite, d) C60 (Buckminsterfullerene or buckyball), e) C540, f) C70, g) Amorphous carbon, and h) single-walled carbon nanotube, or buckytube.
What’s an example of an allotrope?
For example, the allotropes of carbon include diamond (the carbon atoms are bonded together in a tetrahedral lattice arrangement), graphite (the carbon atoms are bonded together in sheets of a hexagonal lattice), graphene (single sheets of graphite), and fullerenes (the carbon atoms are bonded together in spherical.
What is allotrope give two examples?
What is the meaning of the term allotrope?
The term allotrope refers to one or more physical forms of a chemical element that occurs in the same physical state. Allotropes may show differences in chemical and physical properties.
What causes a change in the stability of an allotrope?
The change between allotropic forms is triggered by the same forces that affect other structures, i.e., pressure, light, and temperature. Therefore, the stability of the particular allotropes depends on particular conditions.
When was the concept of allotropy first proposed?
The concept of allotropy was originally proposed in 1841 by the Swedish scientist Baron Jöns Jakob Berzelius (1779–1848).
How are allotropes used to create nanomaterials?
Nanoallotropes, or allotropes of nanomaterials, are nanoporous materials that have the same chemical composition (e.g., Au), but differ in their architecture at the nanoscale (that is, on a scale 10 to 100 times the dimensions of individual atoms). Such nanoallotropes may help create ultra-small electronic devices…
