As compared to a 12C atom, 14C atom has:
Correct answer: B. Two extra neutrons and no extra electrons
- A. Two extra protons and two extra electrons
- B. Two extra neutrons and no extra electrons
- C. Two extra protons but no extra electrons
- D. Two extra neutrons and two extra electrons
Explanation
Isotopes have same number of electrons and protons but different number of neutrons due to different mass number. Carbon-14 having mass number 2 more , therefore number of neutrons are also 2 more.Carbon- 12 = number of neutrons= 12-6= 6. Carbon-14 = number of neutrons = 14-6 = 8.

About Nuclear Physics
Atomic nuclei contain protons and neutrons, with nuclear size, mass defect and binding energy describing their stability. The work covers alpha, beta and gamma decay, decay equations, half-life and decay rate, along with radiation safety and medical applications such as imaging, radiotherapy and tracers.
