Key Differences

Allotropes and Isotopes are concepts that describe variations of elements. Allotropes refer to different structural modifications of the same element, where the element exists in different forms due to variations in the arrangement of atoms.

For example, carbon can exist as graphite, diamond, and graphene, all of which have different atomic structures but are all made of carbon atoms. Isotopes, on the other hand, relate to atoms of the same element that possess different numbers of neutrons, resulting in a variation in atomic mass. Carbon-12 and Carbon-14 are isotopes of carbon. While the former has 6 neutrons, the latter has 8.

In essence, while Allotropes concern the arrangement of atoms, Isotopes revolve around the atomic composition concerning neutrons.
