Question

222 Which of the following equations correctly represents alpha decay of Rn? 86 222 Rn 222 Fr + '18 86 87 226 88 86 222 Rn + He Ra 220 Pb + He o 222 Rn 86 82 222 Rn 218 Po + He 86 84 222 Rn At + 41B 86 85

Answer 1

Alpha decay  is a radioactive decay in which an atomic nucleus emits an alpha particle/helium nucleus.

222 Rn 86 218 Po + He 84 2

Radon undergo alpha decay to form polonium and helium nucleous as major product.

Therefore, option IV is correct
