Please no pictures I need the answer typed out, thank you.
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.
Please no pictures I insufficiency the tally typed quenched, rejoice you.
A radioactive center alpha decadences to comply a sodium-24 center in 14.8 hours. What was the individuality of the former center? Show the nuclear equation that leads you to this tally.
Let X be the center.
Then upon alpha decadence it gives sodium-24.
The balanced reaction is 13 Al 27 —–> 11 Na 23 + 2 He 4
So the former center is Al-27
