The equation shows the radioactive decay of radon-222. 222 86 Rn 218 84 Po + 4
Question:
The equation shows the radioactive decay of radon-222.
22286Rn → 21884Po + 42 α + r
Calculate the total energy output from this decay and state what forms of energy are produced.
(Mass of 22286Rn = 221.970 u, mass of 22286Po = 217.963 u, mass of 4/2 α = 4.002u, 1 u is the unified atomic mass unit = 1.660 × 10−27 kg.)
