What is the half life of the Radioisotope Na24?
It is 15.02 hours.

The halflife of Na24 is 15 hours When there are 1000 atoms of Na24 in a sample a scientist starts a stopwatch The scientist stops the stopwatch at 45 hours there are atoms of Na24 rema?
There will be 125 atoms of Na24 remaining in the sample after 45 hours. This calculation is based on the fact that after 3 half-lives (45 hours/15 hours per half-life), the original 1000 atoms would have reduced by a factor of 2 three times, resulting in 1000/2/2/2 = 125 atoms remaining.
