What is an allotropic form?
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. For example, graphite and diamond are both allotropes of carbon that occur in the solid state.
What are allotropes called?
When an element possess two or more different forms in the same state, they are called allotropes and the phenomenon is known as allotropy. Diamond and graphite are the two allotropes of carbon.
What are allotropes explain with example?
Two or more forms of the same elements in same physical state which differ in their physical properties but have same chemical properties are called allotropic forms or (allotropes) and the phenomenon is called allotropy. Carbon, phosphorus and sulphur are some elements which exhibit allotropy.
What are allotropes Class 11?
Hint: The allotropes are the various structures of the same element. It also refers to one or more physical forms of a chemical element but may show the difference in physical and chemical properties. Therefore it has allotropes. The most common allotropes of carbon are graphite and diamond.
Which is the best definition of the word allotropic?
(ə-lŏt′rə-pē) n. The existence of two or more crystalline or molecular structural forms of an element that have different chemical or physical attributes. al′lo·trop′ic (ăl′ə-trŏp′ĭk, -trō′pĭk), al′lo·trop′i·cal adj.
Which is an example of an allotropic modification?
used to describe different physical forms of the same chemical substance: Diamond and graphite are allotropic forms of carbon. an allotropic modification. See. allotropy. More examples. Ozone is an allotropic form of oxygen. Selenium has several allotropic forms. Natural manganese occurs in four allotropic modifications.
How are allotropes different from other structural forms?
Allotropes are different structural forms of the same element and can exhibit quite different physical properties and chemical behaviours. The change between allotropic forms is triggered by the same forces that affect other structures, i.e. pressure, light, and temperature.
What are the different types of carbon allotropes?
Eight allotropes of carbon: a) diamond, b) graphite, c) lonsdaleite, d) C60 buckminsterfullerene, e) C540, Fullerite f) C70, g) amorphous carbon, and h) single-walled carbon nanotube. Carbon is capable of forming many allotropes due to its valency. Well-known forms of carbon include diamond and graphite.
