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.

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. The existence of different crystalline forms of an element is the same phenomenon that in the case of compounds is called polymorphism.

2020年8月3日 · 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 …

2019年8月11日 · 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.

Carbon (C C) belongs to the family of elements known as non-metals. The bonding between C C atoms (and to other types of atoms) is typically described as covalent bonding where each bond involves two electrons (one from each of the bonded atoms).

The meaning of ALLOTROPY is the existence of a substance and especially an element in two or more different forms (as of crystals) usually in the same phase. How to use allotropy in a sentence.

Allotropes are two or more forms of the same element in the same physical state (solid, liquid, or gas) that differ from each other in their physical, and sometimes chemical, properties. The most notable examples of allotropes are found in groups 14, 15, and 16 of the periodic table.

When the chemical element exists in more than one form, this statement defines allotropy process. 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.

Diamond and graphite are two allotropes of carbon—that is, they are pure forms of the same element that differ in structure. If a chemical element can exist in two or more different forms, the forms are known as allotropes of the element, and this type of behavior is called allotropy.

2024年5月21日 · 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.
