Question

Quizplus · Accepted Answer

Isotopes are variants of elements that have the same number of protons (and therefore the same atomic number) but differ in the number of neutrons in the atomic nucleus. This results in isotopes having different atomic masses but similar chemical properties. Sports, alleles, and races are not related to the concept of isotopes.
