E)amount of radioactivity

Question

Quizplus · Accepted Answer

Isotopes of the same element differ from each other in the number of neutrons in their nuclei. They have the same number of protons and electrons, but different numbers of neutrons, which affects their atomic mass. Valence electron distribution and amount of radioactivity may also differ among isotopes, but these differences are not characteristic of all isotopes of a given element.
