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