Answers & Comments
Answer:
The correct answer is d. (24p, 25e, 28n) and (25p, 25e, 26n) are said to be isotopes. Isotopes are atoms of the same element that have the same number of protons (same atomic number) but different numbers of neutrons (different atomic mass). In this case, both pairs have the same atomic number (number of protons), but different atomic masses (number of neutrons), making them isotopes of each other.
