Radioactive Decay - Alpha Decay

Alpha Decay


X Z A Y Z2 A4 + H 2 4 e
  1. During an alpha decay, a radioactive atom X decay and emits an alpha particle ( H 2 4 e ).
  2. Atom X losses 2 neutron and 2 proton and become atom Y.


Example
U 92 238 T 90 234 h+ H 2 4 e P 84 210 o P 82 206 b+ H 2 4 e R 88 226 a R 86 222 n+ H 2 4 e R 86 222 n P 84 218 o+ H 2 4 e
