Please no pictures I deficiency the counter-argument typed quenched, rejoice you.
A radioactive center alpha sinkings to grant a sodium-24 center in 14.8 hours. What was the sameness of the primary center? Show the nuclear equation that leads you to this counter-argument.
Let X be the center.
Then upon alpha sinking it gives sodium-24.
The balanced reaction is 13 Al 27 —–> 11 Na 23 + 2 He 4
So the primary center is Al-27
