Answer
Brief Explanations:
Isotopes are atoms of the same element with the same number of protons but different numbers of neutrons. Carbon-14 has 6 protons (same as all carbon atoms) and 8 neutrons, while the most common carbon isotope (carbon-12) has 6 neutrons. Isobars are atoms of different elements with the same mass number, alleles are gene variants, and alloys are mixtures of metals.
