D) Isotopes of the same element don't usually have the same properties.
E) Some elements have 3 or more naturally occurring isotopes.

Question

Quizplus · Accepted Answer

Isotopes are atoms of the same element that have the same number of protons but different numbers of neutrons, which results in a different atomic mass. Some elements have 3 or more naturally occurring isotopes, such as carbon, which has isotopes with atomic masses of 12, 13, and 14. Therefore, option E is the true statement among the given choices.
