If atom X undergoes radioactive decay and becomes atom Y with a half-life of five minutes. After 10 minutes, all number of X atoms have completely turned into to Y atoms.

Question

Quizplus · Accepted Answer

The half-life concept means that after 5 minutes, only half of the X atoms would have decayed into Y atoms. After another 5 minutes (totaling 10 minutes), only half of the remaining X atoms would decay, leaving 25% of the original X atoms.
