Does n show allotropy
The term allotropy is used for elements only, not for compounds. The more general term, used for any compound, is polymorphism, although its use is usually restricted to solid materials such as crystals. Allotropy refers only to different forms of an element within the same physical phase (the state of matter, such … See more 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, … See more Allotropes are different structural forms of the same element and can exhibit quite different physical properties and chemical behaviours.

N 2 (g) is stable due to its electronic structure: the bond between the two nitrogen atoms of N 2 is a triple covalent bond which is strong and hard to break.
WebJan 15, 2024 · Allotropy can be defined as the phenomenon in which an element can exist in two or more forms. While allotropes do retain identical physical states and usual chemical properties, they do not necessarily retain the same chemical activity or molecular structure. Several p-block elements showcase allotropic nature.
