What Are the Different Physical Forms of an Element Called

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 different versions of an element called?

Atoms of the same element that differ in their numbers of neutrons are called isotopes. Many isotopes occur naturally. Usually one or two isotopes of an element are the most stable and common.

What are different forms of the same element in the same state called?

Allotropes are different forms of the same element, in the same state. Graphite ,graphene and diamond are allotropes of the same element (carbon) in the same state (solid).
