What is an allotrope 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 allotropes explain?

allotrope. / (ˈæləˌtrəʊp) / noun. any of two or more physical forms in which an element can existdiamond and graphite are allotropes of carbon.

What is an allotrope Class 10?

Allotropes are two or more forms of the same element existing in the same physical state (either solid, liquid, or gas) that differ from each other in their physical, and sometimes also in chemical, properties.

What is allotropy Class 11?

The phenomenon of existence of an element in two or more forms which have different physical properties but identical chemical properties is called allotropy and the different forms are called allotropes.

What are allotropes 12?

In a physical state, chemical elements can exist in different arrangements, which is called the allotropes. The bonding patterns are different in allotropes and also they are the structural modifications of an element. c) In the same phase, an element that can exist in different forms are called allotropes.

What are allotropes of phosphorus?

The main allotropes of phosphorus include the white phosphorus, red phosphorus and black phosphorus. In addition to these, there also exists a violet phosphorus.

What is Allotropy and Catenation?

The key difference between catenation and allotropy is that catenation refers to the biding of an element to itself, forming chain or ring structures, whereas allotropy refers to the existence of different physical forms of the same chemical element.

What causes Allotropy?

At different temperature condition pressure and atmospheric condition same elements is stable in different geometry. Ability of elements like carbon to show the property of forming long and cyclic giant structure give rise to allotropes.

What are allotropes class 8th?

Answer: The word allotrope refers to one or more physical forms of a chemical substance that exist in the same physical state. Allotropes can exhibit chemical and physical variations. Diamond and Graphite, both are known as the allotropes of carbon.

What is allotropy Vedantu?

Another allotropy definition can be written as “allotropy is the capacity of the element to exist in more than one form. Each form of the element has different physical properties. But these allotropic forms of elements are identical in their chemical properties. These different forms are called allotropes.

Why is fullerene so called?

The scientists who vaporized the graphite to produce C60 named the new carbon allotrope buckminsterfullerene (shortened to fullerenes or buckyballs) because the geodesic domes designed by inventor and architect Buckminster Fuller provided a clue to the molecule’s structure.

What are allotropes examples?

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.
