Correct answer and explanation

Correct answer: Isotopes

Explanation: āœ… Correct Answer: A) Isotopes šŸ“š Explanation: Isotopes are distinct variants of a particular chemical element. While they possess the exact same number of protons (atomic number), they have a different number of neutrons, which heavily alters their atomic mass number. For example, Carbon-12 and Carbon-14 are both isotopes of carbon, but the latter is highly radioactive.
