Difference between isotopes and allotropes?
|
Isotopes- 2 or more forms of the same element
Allotropes- two or more different physical forms in which an element can exist Allotropes are elements on the periodic table that have more than one crystalline form . There are three forms of the element carbon : Diamond, Graphite, and Fullerenes. Isotopes are atoms of the same element with the same atomic number but have a different mass number |
