As nouns the difference between isotope and allotrope
is that isotope is any of two or more forms of an element where the atoms have the same number of protons, but a different number of neutrons within their nuclei. As a consequence, atoms for the same isotope will have the same atomic number but a different mass number (atomic weight) while allotrope is any form of an element that has a distinctly different molecular structure to another form of the same element.
As a verb isotope
is to define or demonstrate an isotopy of (one map with another).
