Analyze the relationship between Carbon-12 and Carbon-14

Carbon-12 and Carbon-14 are atoms of the same element (carbon, atomic number 6) with different mass numbers (12 and 14).

Determine the subatomic differences

• Carbon-12 has 6 protons and 6 neutrons.
• Carbon-14 has 6 protons and 8 neutrons.
• Atoms of the same element with different numbers of neutrons are defined as isotopes.

Match with the correct multiple-choice option

• Option B correctly identifies them as isotopes because they have a different number of neutrons.
