Question

3. Assume that a sample decays with a given half-life. Will you be able to observe when the sample has completely decayed? Why or why not?

Answer 1

No

Step-by-step explanation:

It will never decay to zero

after one half life there is 1/2 left

after the next half life thee is 1/2 * 1/2 = 1/4 left

then 1/8th then 1/16 th then 1/32 1/64 1/128 ........to infinity

while htere is a VERY small amount left , there will never be ZERO left
