Understanding Isotopes and Mass Numbers
To determine why the correct answer is option 'C', we first need to understand the concepts of isotopes and mass numbers.
Mass Number
- The mass number of an atom is the total number of protons and neutrons in its nucleus.
- For carbon (C), the atomic number is 6, which means it has 6 protons.
Carbon's Isotopes
- Isotopes are atoms of the same element that have the same number of protons but different numbers of neutrons.
- If an atom has a mass number of 14, it means it has 14 - 6 = 8 neutrons.
- Therefore, an atom with a mass number of 14 and 8 neutrons is indeed a carbon isotope, specifically Carbon-14.
Why Not Isobar or Other Options?
- An isobar refers to atoms that have the same mass number but different elements. Since 14 is a specific mass number for carbon, it cannot be an isobar.
- Oxygen has an atomic number of 8, which would require it to have a mass number of 14 - 8 = 6 neutrons (not 8). Thus, it cannot be an isotope or isobar of oxygen.
Conclusion
- The atom in question, with a mass number of 14 and 8 neutrons, is an isotope of carbon, confirming that option 'C' is correct.
This understanding of isotopes clearly illustrates why the answer is 'C' and not any of the other options.
