Radon-220 is radioactive and decays to polonium-216 with the emission of an α-particle. The equation for the radioactive decay is shown.86220Rn→84216Po+24 .He how many neutrons are in the radon and polonium nuclei?
Correct answer: B. B
- A. A
- B. B
- C. C
- D. D
Explanation
Number of neutrons in raden=220-86=134 Number of neutrons in polonium=216-84=132

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.
