Asked by Student101
A radioactive nucleus alpha decays to yield a sodium-24 nucleus in 14.8 hours. What was the identity of the original nucleus? Show the nuclear equation that leads you to this answer.
13 X 28 --> 11 Na 24 + 2 He 4
look at the periodic table for atomic number 13 --- that is the element you are looking for. If I remember correctly, it is aluminum. Should Al should replace X above? so it would be 13 Al 28 ---> 11 Na 24 + 2 He 4??
