Explain the term allotropy
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. WebVerified by Toppr. (a) Inert pair effect: On moving down the group, the tendency of s electrons to participate in chemical bonding decreases. This effect is called inert pair effect. Due to this, in group 13, the stability of +3 oxidation state decreases and the stability of +1 oxidation state increases. (b) Allotropy:

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. Allotropes are different structural modifications of an element: the atoms of the element are bonded together in different manners. For example, the allotropes …
